And maybe the dreamers are not the real dreamers. Why do you think China don't wants that trash from the west anymore. Because most parts of these planet just start to produce large amounts of plastic trash. Very soon they will have a mountain of trash that looks like nothing copared to what you guys produced. Or do you think your the only one that can enjoy a nive crispy chocolate bar. You burried your own children, that's the kind of assholes you are.

A "filé au plastic" with a pinch of enriched uranium fresh from the sea would be nice for the moment. To make me feel happy.

Peugeot CEO outlines ambitious plan to re-enter U.S., go electric
https://www.reuters.com/article/us-autoshow-detroit-peugeot/peugeot-ceo-outlines-ambitious-plan-to-re-enter-u-s-go-electric-idUSKBN1F706J

Tavares said in his speech that by 2025 “the PSA Group will be 100 percent electrified,” which can mean all electric or hybrid. Tavares and a company spokesman clarified that electrification will be an option on all the automaker’s vehicles by that time. Global automakers have announced $90 billion in investments to electrify future vehicles to comply with regulations to curb carbon dioxide emissions.

By 2030, Tavares said, 80 percent of the automaker’s vehicles will offer the ability to pilot themselves under limited conditions, and 10 percent will be capable of autonomous driving.

I would expect to see some disappointing "earnings news" from the major "old line" auto makers over the next FEW YEARS.

1)  We may have "peaked" on a "cyclical basis" and thus....may be heading towards a "lull" as we head for the next "trough" in earnings.

2)  The old line major auto makers are having to sell BOTH their "old line" gasoline powered cars....while transitioning to hybrids and all electrics (and eventually....to all electrics PERIOD).  That is an expensive proposition.

Here is part of an advertisement on the Fox News website: FCC Approves Wireless Electricity; Changes Everything

Quote
The biggest mass manufacturing craze in a century set to begin any day now for new…

“NanoCrystal Electricity”

It will magically power everything – lamps, TVs, alarm clocks, radios, coffee makers, washers, dryers, refrigerators, toaster ovens, blenders… you name it – without a plug!
...
In fact, soon you won’t even have to stop for gas

That’s because this new NanoCrystal Electricity is going to put an end to the combustion engine and send electric car production through the roof.

With this new electricity, your car will be able to magically power itself as you’re waiting at a red light… or pulling into a parking lot… or even as you drive down the freeway.

Elon Musk and the geniuses at Tesla were the visionaries who saw this coming.

But the mainstream auto makers are now waking up fast, realizing NanoCrystal Electricity technology is the future.

The 2018 Mercedes-Benz S550e already has the necessary receiver onboard – ready to roll.

Volkswagen is also planning to put NanoCrystal Electricity technology in their fleet of cars.

And Volvo just sent shockwaves around the world: It announced plans to dump its entire fleet of gas-guzzlers and replace them with electric cars or hybrids by 2019.

Make no mistake: Every carmaker in the world is frantically pursuing what I call NanoCrystal Electricity technology. 

Some experts predict this will be a standard feature for every electric vehicle by 2020 at the latest.

For good reason: With this groundbreaking new technology readily available, why would anyone want to buy an electric car that requires you to fiddle with a dangerous and dirty high-voltage plug, when you can glide over a charger with RF technology?

No more messing with foul-smelling gas pumps either.

Since analysts are saying that 35% of all vehicles on the road will be electric within the next two decades, and with populations increasing exponentially around the globe, we are truly witnessing a revolutionary movement
...
Arctic ice is healthy for children and other living things.

NanoCrystal?  :D
That's the lamest name I've heard in a while.

Is it known what happens to your body's cells when wireless electricity goes through them to power 1000W appliances? And here I was worried about WiFi electrosmog.

I'd like to go back to the issue about cars being set on fire.

There are times when people act badly.  People of all colors damage private property. 

With self-driving cars, robotaxis, a company could rapidly move all their cars out of an area where trouble was happening.  There would be no need to leave cars parked in neighborhoods where vandalism and break ins are a problem. 

Worst case, if you happen to live in an area where parked vehicles are more frequently damaged, you'll have to order your ride a few minutes earlier in order for a car to arrive from a few miles away.

Just adding to that, a robo-car has much better defenses than a normal car: its cameras can record the attackers and transmit their photos. It can call security/police when it senses it is being attacked. And its algorithms can even include moving away from suspected aggressors. Besides, such cars would normally park outside urban areas.

Even better: cars could spot someone setting cars on fire, call police with photos, and leave the area.

Does that depend on petrol stations becoming much more scarce or maybe there are alternatives like methylated spirits? Are all lawnmowers and similar machinery all going battery &/or electric also or might petrol stations on a smaller throughput scale persist quite some time? Or maybe if you are going to vandalise, fuel tank locks are easy to break and make convenient 'free' source?

Considering the progression of drones from spying to armed semiautonomous kill vehicles maybe the autonomous cars will fight back? 
 I saw film taken of the recent Thomas fire that came from high altitude drones. I am quite sure they have been involved with CAMP ( campaign agains't marijuana production ) although I have no proof.
When does spying in the name of fighting crime or pot production switch to enforcing borders and ultimately to armed kill vehicles. All in the name of first fighting terror, then fighting crime. How would organized car burning be viewed ... Terrorism?  ELF is most definatly viewed as an Eco-terrorist organization for burning down houses.
 I don't trust the whole movement towards autonomous vehicles because it will very much enable the mission creep that facilities armed autonomous vehicles that are currently employed by the military. I don't know why I should trust police with this technology , and ultimately they will be using it.

Yes.  Most ICE car fires are causes by leaks of flammable fluids an EV doesn’t have.  This article compares the various causes of car fires, EV vs. ICE — mostly accidental, though they briefly consider arson:
Quote
When comparing collisions only, EVs are safer 30-3 or 10-1, yet collisions are only responsible for a third of the fires. In general, the public and media has dismissed the other two thirds causes for fire in an automobile. They have dismissed the fact that fuel systems are still the number one cause of fires and this will never be the case for the BEV. In fact, 4  of HSW’s top 5 causes for fire including (fluid spills, overheating engines, and catalytic converters) will never be the cause of a fire in a BEV.
https://insideevs.com/op-ed-top-10-causes-of-automobile-fires-ev-vs-ice/

And here’s the result of intentional fires set to test what would happen to a big Tesla Powerpack:
https://electrek.co/2016/12/19/tesla-fire-powerpack-test-safety/

Which is not to say an EV can’t be set on fire:  :(

Sigmetnow: most intentional fires are caused by people lighting the interior of the car on fire, likely using petrol to light it. The drive train isn’t really related to the interior furnishings, so I’d expect the EV and ICEV to burn equally well during a riot.

But as crandles points out, if there’s a lot of EVs, there’s less ready availability of petrol for rioters to use to light cars on fire. There’s still lots of energy in the car, it’s just not as easy to repurpose.

Once the heat is sufficient to set off the fuel in the car's tank there will be a fireball.  EV batteries burn more slowly, sort of a smoldering fire.

Why is everyone so obsessed with car fires? As a former fireman, albeit a loong time ago, I'm simply bored by the subject. Car fires will still be there with EVs, only different. Man discovered how to control fire a long time ago, without petrol. MSB (Swedish Civil Contingencies Agency) has a long and elaborate writeup on everything considering EVs and fires as well, but it's all in Swedish.

Guess I primed the car fires with one line here:
https://forum.arctic-sea-ice.net/index.php/topic,438.msg139079.html#msg139079
The post was mainly about legal issues that needs to be considered BEFORE we will see any level 4 or 5 cars in traffic, then this line:
Then we might also consider how we humans would treat automated vehicles in traffic.
Bob made one reply and then the car fires started by Alexanders comment.

Another rather funny observation, on this page everyone has stayed on topic and mentioned cars in their posts except three people. I myself made one totally off topic comment, Alexander555 made two, Neven made three.  ;D

Car fires will still be there with EVs

But the frequency?  Car fires are much more common that most people realize. 

Quote
Cars bursting into flames after a crash is a pretty rare event. According to the National Fire Protection Association, of the 174,000 vehicle fires in 2015:

49% were due to mechanical failure or malfunction
11% were due to leaks or breaks
23% were due to electrical failures
5% were due to the vehicle being exposed to another type of fire
3% were due to a car crash or rollover
(the remaining causes were not listed)

92% were due to mechanical failures, leaks, and electrical problems.  160,080.  About 439 per day.

Tesla had two battery fires prior to putting the shield underneath the battery pack.  There was one unexplained fire while a Tesla was charging in Sweden(?).  I'm not aware of any other non-crash related fires.  And one could argue that the two battery fires resulting from running over metal junk in the road could be attributed to crash.

Is it likely that EVs will experience far fewer fires than ICEVs?  Or might the number increase as some EVs get old?  I would think the circuit breakers would still work.

I agree Bob, they are much more common than most people realize. But as you probably saw in the first image I posted here,
https://forum.arctic-sea-ice.net/index.php/topic,438.msg139166.html#msg139166
they are also rather consistent, at least in Sweden. What I also believe is rather consistent, are the frauds. Back in the 80's, I know for a fact that we had many fires where we knew who was responsible, proving it is another issue... So I do belive that these numbers presented by Larmtjänst (911) and insurance companies are more true, than not.

During January to September 2017, insurance companies have received about 6000 reported claims due to car fires. 60 percent are estimated to be deliberately set on fire.

I'd expect that any vehicles carrying many liters of flammable liquids would experience more flare ups than those without. Circuit breakers are designed to fail in the open position, although the contacts certainly can weld themselves together. Fusible links provide the final safety.


I think this discussion was actually about vandals/luddites destroying parked EVs in preference to ICE vehicles.
In San Francisco buses carrying high tech workers have recently been attacked, probably as a reaction to the soaring house prices that have driven some into homelessness. As long as EVs are perceived as the vehicles of the elite, some will be attacked. Once they become popular with the masses this form of vandalism should end. 8)

People in general imagine that, reality is a bit different.
I once had a heated discussion with a friend. He was upset after seeing someone smoking at a gas station. Everyone would agree, it's stupid. But when I tried to explain that during summer the air/fuel ratio would be off and it's at least a bit safer then. Then he was mad at me. :)

I asked him how many times have you turned off your (open flame) propane fridge in your motor home while refuelling?
-Never.
Has the gas station ever exploded or caught fire?
-No.
Why is that?
Adding an image depicting the flammable air/fuel ratio in closed containers for gasoline and ethanol. In the open air during summer it's almost impossible to ignite gasoline fumes. Only in Hollywood.

Even if 60% of car fires are deliberate the number of non-deliberate is rather high.  I continue to wonder if EVs will set themselves on fire at the same rate.  I suspect not.

As for intentional damage to EVs that should be very minimal with robotaxis.  Just don't leave them in places where they would be accessible to vandals.  If there is a large area where vandalism is more likely then set up a fenced, attended service center where the EVs can charge, be cleaned, and stay safe until called out for a ride.

most car fires happen due to broken or leaking fuel tubes and in the process fuel dropping onto very hot parts like exhaust etc.

again most cases are due to an  impact of some kind, i.e. accidents and only in very very rare cases, compared to the total number of vehicles, is there another reason than those mentioned.

We will see that soon Bob, when we get more EVs on the road.

One of the cases I've read of, a lightly crashed hybrid (again at MSB and in Swedish), caught fire long after the crash. They even test drove the car after the crash and then parked it outside. The only visible trace of where the fire could have started was some DC arcing on a battery connection (yes there were fuses but that didn't help).
But that's also why one of the recommendations to rescue personell now, is to disconnect batteries after a crash on EVs and hybrids. That said, there are few reasons to believe that the batteries themselves should cause any major problems as we progress. They just need to deal with them differently after crashes, many of these earlier fires will probably not happen in the future.

Even if 60% of car fires are deliberate the number of non-deliberate is rather high.  I continue to wonder if EVs will set themselves on fire at the same rate.  I suspect not.
We will see that soon Bob, when we get more EVs on the road.

One of the cases I've read of, a lightly crashed hybrid (again at MSB and in Swedish), caught fire long after the crash. They even test drove the car after the crash and then parked it outside. The only visible trace of where the fire could have started was some DC arcing on a battery connection (yes there were fuses but that didn't help).
But that's also why one of the recommendations to rescue personell now, is to disconnect batteries after a crash on EVs and hybrids. That said, there are few reasons to believe that the batteries themselves should cause any major problems as we progress. They just need to deal with them differently after crashes, many of these earlier fires will probably not happen in the future.

Yes, but that's a crash related fire.  We had a least one similar fire in an EV (or PHEV) some days after the crash.  Now the procedure is for batteries to be discharged when wrecked EVs are taken to storage yards.  I think it's also the case that gas tanks are emptied before wrecks are stored.

There was another EV fire (IIRC) that started with a minor crash where it seems like some electrical line was pinched and the arching ignited the headliner (?).  That, of course, could happen with any vehicle regardless of how it was powered. Heck, I almost burned up my sailboat that way.  (My wiring mistake, not a crash.)

People in general imagine that, reality is a bit different.
I once had a heated discussion with a friend. He was upset after seeing someone smoking at a gas station. Everyone would agree, it's stupid. But when I tried to explain that during summer the air/fuel ratio would be off and it's at least a bit safer then. Then he was mad at me. :)

I asked him how many times have you turned off your (open flame) propane fridge in your motor home while refuelling?
-Never.
Has the gas station ever exploded or caught fire?
-No.
Why is that?
Adding an image depicting the flammable air/fuel ratio in closed containers for gasoline and ethanol. In the open air during summer it's almost impossible to ignite gasoline fumes. Only in Hollywood.
But of course gas stations are not in closed containers and even if some part of it would have air which is saturated in fuel vapour at summer air temperature it will be diluted to a flammable mixture by air currents at least in the transition from saturated vapour to surrounding fresh air.
Maybe your friend was exasperated by your lack of logic?

This is fun (and sort of the antidote of burning cars, but not really):

Popular Mechanics:  The Floating Electric Car That Was Born From Tragedy
Quote
The devastating earthquake and tsunami that hit Japan in 2011 inspired numerous innovations meant to prevent future disasters. That includes one man's dream of a floating car.

Hideo Tsurumaki, a former Toyota employee, witnessed people trying to escape the tidal onslaught in their cars only to be swept away in the destruction. He later founded Fomm Corp., which aims to build small, waterproof cars that can actually float. He sees them as not just potential ways to get around, but as safety investments.

Green Car Reports:  What you need to know about electric-car namesake Nikola Tesla
Quote
This month marks the 75th year since the death of famed inventor and and electrical innovator Nikola Tesla, a man whose life is as interesting as his technical achievements.

Tesla, a Serbian who was born in what's now Croatia, brought the world numerous innovations in electricity that, to this day, define how we live.
...
His time with Edison in the United States would be short-lived; Tesla claimed Edison backed out of a deal where Nikola was offered $50,000 to solve a series of problems Edison's researchers couldn't pin down.

Tesla must have been a trusting sort, as he then partnered with two investors to create Tesla Electric Light and Manufacturing.

All the patents Tesla filed were attached to the company, and his partners would steal the company out from under Tesla, leaving him penniless and without his own inventions.
...
He remains legendary and revered today among engineers and inventors for making the idea of alternating current a practical reality, allowing electricity to be transmitted over long distances.
...
While Edison remains far more famous, Tesla's creation eventually overwhelmed the direct current pioneered by Edison.

This article has a rather detailed video explaining to first responders how to safely deal with the high voltage circuits and extrication considerations in a Tesla Model X.

Oh, and per Tesla:  the first big rule for an EV battery fire is:  lots and lots of water!  You must keep cooling the battery to prevent thermal runaway.  Keep putting water on it for... a long time... and beware of the risk for later flare-ups.

Jalopnik:  That Fleet Of Electric Cars The LAPD Paid At Least $2.9 Million For? It's Barely Touched Them

Quote
In June of 2016, BMW announced it won a contract to supply the Los Angeles Police Department [LAPD] with 100 electric cars—a multi-million-dollar program the chief said “made sense for taxpayers and for the environment.” Hah. The LAPD has barely used them.

Both the local and LAPD leadership talked boldly in 2016 about greener practices and technologies, with Los Angeles Mayor Eric Garcetti telling the Los Angeles Times we “should be thinking green in everything we do.” The LA Times reported that the BMW i3 fleet, made up of 100 cars on lease by LAPD, would cost about $1.4 million over three years—$387 a month per car, according to the story. An additional $1.5 million went into infrastructure investment for electric cars.

But even if the folks in LA are thinking about ways to be green, the practice part seems to be where they’re missing the point. An investigation by CBS Los Angeles found the cars, meant to be used for non-emergency purposes like outreach and police business instead of patrols or chases, haven’t really been used at all.

Records searched by CBS Los Angeles found that the LAPD’s BMWs, many of which have been in use for more than a year, had between a few hundred and a few thousand miles on them. A car that had an in-service date of May 27, 2016 only had 400 miles on it at the time of the investigation, according to the outlet

Here’s Electrek’s article on this.  I note from the data shown in the video, it appears only 9 cars had less than 1,000 miles; many had several thousand miles.  But yes, like the general public, it seems the LAPD has some educating to do. 

LAPD is apparently barely using its large fleet of BMW i3 electric vehicles

It would also be good to compare with other fleets of longer-range EVs:

most car fires happen due to broken or leaking fuel tubes and in the process fuel dropping onto very hot parts like exhaust etc.

again most cases are due to an  impact of some kind, i.e. accidents and only in very very rare cases, compared to the total number of vehicles, is there another reason than those mentioned.

US - "3% were due to a car crash or rollover"

the wording was "broken or leaking fuel tubes" I.E. accidents so yes, 3% would make for an example but not for the entire story, true that.

of course there are many more ways like brittle rubber tubes, failing joints and seals, human errors like forgetting to tighten screws of the fuel system etc. and last but not least exhaust touching plastic like it was the case with some porsches a few years ago.

the point was that in most cases it's liquids like oil and fuel on very hot parts like exhaust system, no matter what the cause of the leak was and yes it could be breaking fluid and others stuff like dropping insulation material etc. as well.

BMW coming out with a Tesla 3 competitor in 2021 with 435 mile range and prices similar to the Tesla 3.

By 2025....you can wee why we will likely be talking about cars on the introductory level with about 250 miles of range (instead of 100 - 150 now)....and cars at the high end of 600+ (there is already a manufacturer coming out next year with a car that gets 600 miles of range).

Maybe your friend was exasperated by your lack of logic?
The tanks are. Inside the tank the air/fuel mixture is normally too rich to ignite. The blue temperature area for petrol in the image I attached above is the only area where you can ignite the vapour in a tank.
At the nozzle you can of course find an igniteable air/gas mixture, if you hold your lighter there then your'e simply stupid. If you try to ignite it there anyway, it will normally not ignite the contents of the tank.
A bit further away from the nozzle, like the open flame in my friends fridge or the guy he mentioned (he wasn't filling up his car), it will be almost impossible because the mixture is too lean.
The attached image was from one of many studies made by MSB regarding the risks of fires in gas stations when E85 was introduced in Sweden.
https://www.msb.se/en/
If you wish to read those papers I can probably find them for you. Just ask.

Edit; here's a good example of what not to do. Cold, lighter, nozzle. Wonderfully stupid.

Still no Hollywood flames or explosion though.

There's no need for that sort of range.  It's just unnecessary weight and expense.

Enough range to drive meal to meal.  8 to 12 at 70 mph is 280 miles. 

We need somewhat faster charge rates than we now have. 

'Nuf.

Robotaxis probably need only 100 mile ranges.  If that.  Run the morning commute and work 'part time' until it's time to run the afternoon commute.  Charge up during the day if needed and fully charge at night.

That's so far from what is technologically possible today that bringing it into the discussion has no value.

Find a proven charging system that will do 10% better than Tesla Superchargers and EVs.  If you can find something 10% better, that is proven, then we can extend the speculation.

600 mile range.  Why would anyone need that?  We now drive ICEVs with half that range and we don't complain.

A short return to bikes and traffic problems. People are people, everywhere.
Swedish police are troubled by tuned up electric bikes and the speed tuning kits that are sold, which effectively turns the electric bikes into illegal motorcycles. They hope that the bike industry will fix it. No wonder, the police here hardly have any traffic officers to do the job.
