Anecdote:  a friend of mine and her husband drive down to Florida to visit her mother once or twice a year, a trip she describes as just at the limit of what they can comfortably do in one day.  “If it took any longer, we’d fly.”


If the purpose of a lower highway speed limit is to save energy, my first thought of course is that driving an EV would save much more energy, at any speed, compared to the energy wasted in heat and friction between all the parts of an ICE vehicle.

But even in ICE transportation, much energy would be saved by using Driver Assistance technology — active cruise control, for instance, which maintains a chosen following distance — rather than inconstant, impatient human control.  A benefit most often cited by users of Tesla Autopilot is how much less stress they feel during a trip (even when they didn’t think driving was very stressful before), and how much more rested they are afterward, by letting the car do the driving.  Lanes restricted to emergency vehicles would not be used enough, and would just make other lanes more crowded.  But a lane with mandated ADAS, which only could go as fast as traffic allowed, might make sense.  Like with what happened with HOV lanes, drivers could select cars allowing them to use this potentially faster, less congested, and no doubt more polite option. Even if they don’t care about saving energy. 8)

And yes, this would be a step toward the days of full self driving.

Terry

Because there’s none where I live, and buses don’t go to all destinations.

Edit:  Well, there are school buses, but stealing one of those for a personal cross-country trip would be frowned upon. ;)

That sounds like something that a few dollars could change.
When Trailways was a thing they had express service between major destinations that included a card table, sandwiches and drinks, pillows, a blanket and a stewardess - all at the same price as a Greyhound.
Imagine what could be done if the government tossed in a few bucks!

Speed limits set only five miles per hour below engineering recommendations produce a statistically significant decrease in total, fatal and injury crashes, and property-damage-only crashes, according to a group of Penn State researchers.

"If (however) you lower the speed limit by 10, 15, 25 miles per hour, or more, drivers stop paying attention," said Vikash Gayah, assistant professor of civil engineering. "We found there was an increase in fatal and injury crashes at locations with posted speed limits set 10 miles per hour or more below engineering recommendations."

This is a very poor, rural area.  Much of the population lacks the money for adequate food or clothing, let alone bus tickets.  The county struggles to simply keep emergency services funded.  Even if buses were available, there would be next to no demand, and no money to support them.  Makes no sense.

  Air pollution particles found on foetal side of placentas – study

Research finds black carbon breathed by mothers can cross into unborn children

https://www.theguardian.com/environment/2019/sep/17/air-pollution-particles-found-on-foetal-side-of-placentas-study
  by Damian Carrington


 Quotes:
Air pollution particles have been found on the foetal side of placentas, indicating that unborn babies are directly exposed to the black carbon produced by motor traffic and fuel burning.

The research is the first study to show the placental barrier can be penetrated by particles breathed in by the mother. It found thousands of the tiny particles per cubic millimetre of tissue in every placenta analysed.

Damage to foetuses has lifelong consequences and Prof Tim Nawrot at Hasselt University in Belgium, who led the study, said: “This is the most vulnerable period of life. All the organ systems are in development.

A comprehensive global review concluded that air pollution may be damaging every organ and virtually every cell in the human body. Nanoparticles have also been found to cross the blood-brain barrier and billions have been found in the hearts of young city dwellers.

-----

While the advise in the article is to avoid busy roads etc...
The best advise should be to take away the cause and not fight the effect: In other words: Don't use personal cars.

While ICE's have the toxic exhaust fumes, both the ICE and EV shed nano-particles, microplastics from tyre wear. Remember this next time you drive past a pregnant woman, past children or a school.
Please, it is an emergency!

edit: Leave your car home for a day or more and use public transport, if available (maybe you need to walk or cycle a bit to the stop).
It's a start. In rural parts you might have interesting conversations :) . Shared transport yeah

So, spend more time traveling, on the side of the road, breathing in even more gas and tyre particles, even deeper than usual because of your increased heart and respiratory rate, without the benefit of a vehicle’s air filtration system?

Or does everyone walking and cycling wear gas masks?

The plot below shows the subsequent evolution in pollution levels inside the vehicle and inside the bubble. In less than two minutes, the HEPA filtration system had scrubbed the air in Model X, bringing pollution levels from an extremely dangerous 1,000 µg/m3 to levels so low as to be undetectable (below the noise floor) by our instruments, allowing us to remove our gas masks and breathe fresh air while sitting inside a bubble of pollution.

If the HEPA filter does all that's claimed, why are so many complaining of the terrible odors from Tesla ACs? Shouldn't any decent air filter be capable of removing odors?

Owners report solving this problem the same way that works for all other “decent” cars:  parking the car and setting the heat on full for an hour or two to eliminate mold and bacteria that accumulates in any humid system (not necessarily in the filter).

Because I drive fewer miles than average, I only need to replace my car tires every 5 years so.  How often do you replace your bike tires?  I need to buy new walking shoes every year or two because the soles wear out.  Let’s count those causes, too!

The Tesla HEPA system might just be removing more pollutants from the environment than the car emits.  We can’t afford the time for “natural” solutions to fix the situation we’ve gotten ourselves into — if they even can.

How strange. I do did drive an excessive number of miles, some I'm sure in "decent"? cars, and I never encountered a similar problem. You don't suppose the engineers could have missed something as rudimentary as providing adequate drainage for the condensate that builds on all AC evaporators do you?

The tire/asphalt dust issue is an externality, just like CO2 from the exhaust.  Typically externalities are addressed by penalties and taxation. Unfortunately, the car lobbies have captured the regulators.

So as usual, the rich will fix the problem for themselves, will breathe clean and filtered air, the poor will suffer and die.

Pass the Oxygen Jeeves. Yes, the one in the silver chalice. Then scuttle back to your hovel, and make sure you seal the airlock behind you.

UPS Gets FAA Nod for Widespread Drone Deliveries
https://www.wsj.com/articles/ups-gets-faa-nod-for-widespread-drone-deliveries-11569939601
http://www.uasmagazine.com/articles/2072/ups-flight-forward-gains-faa-approval-to-launch-drone-airline
https://techxplore.com/news/2019-10-ups-drone-airline.html

UPS subsidiary UPS Flight Forward Inc. today announced it has received the U.S. government’s first full Part 135 Standard certification to operate a drone airline. United Parcel Service Inc. said it received the first-of-its-kind federal approval to start setting up a fleet of unmanned aircraft to deliver health supplies and eventually consumer packages potentially throughout the U.S.

The U.S. Federal Aviation Administration (FAA) awarded UPS Flight Forward a Part 135 Standard certification on Friday. The UPS subsidiary immediately launched the first drone delivery flight by any company under Part 135 Standard at WakeMed’s hospital campus in Raleigh, N.C. That flight, using a Matternet M2 quadcopter, was flown under a government exemption allowing for a beyond visual line of sight (BVLOS) operation, also a first in the U.S. for a regular revenue-generating delivery.

The FAA’s Part 135 Standard certification has no limits on the size or scope of operations. It is the highest level of certification, one that no other company has attained. UPS Flight Forward’s certificate permits the company to fly an unlimited number of drones with an unlimited number of remote operators in command. This enables UPS to scale its operations to meet customer demand. Part 135 Standard also permits the drone and cargo to exceed 55 pounds and fly at night, previous restrictions governing earlier UPS flights.

Even before getting the airline designation, UPS Flight Forward, as the subsidiary is called, has operated more than 1,000 flights at Wake Forest University's medical center in Raleigh, North Carolina.

Going forward, UPS Flight Forward says it has a long-term plan with several milestones:

- Expansion of the UPS Flight Forward delivery service to new hospitals and medical campuses around the country;
- Rapid build-out of ground-based, detect-and-avoid technologies to verify drone safety while enabling future service expansion;
- Construction of a centralized operations control center;
- Regular and frequent BVLOS drone flights;
- Partnerships with additional drone manufacturers to build new drones with varying cargo capacities; and
- Adding new services outside of the healthcare industry, including the transport of special commodities and other regulated goods.

UPS believes the earliest commercially viable uses of drones will be for same-day deliveries, for augmenting truck-borne deliveries in rural areas, and for larger drones that could carry cargo of up to a ton from one rural area to another. Price said the latter idea is still years away.
