Say... some time within the 2020-2028 (next U.S. Democratic administration) timeframe?
I think EVs have broken free from the gravity field of US politics. EVs are global and, I think, all non-Chinese manufacturers realize that they better get cracking with their own EVs least China and Tesla eat their breakfast, lunch and dinner.
A Crush the Hog program in the US would have to wait on a return to sanity.
Wouldn't be even better from a LCA-perspective to swap the ICE for an electric engine and batteries? Crushing a car and recycling costs a lot more energy than just re-using the car right away.
It's kind of like putting a gas engine into a horse drawn wagon. It's been tried and it just doesn't work out all that well. Better to design the car body around the battery pack rather than try to fit a battery pack into a vehicle designed for a fueled engine and transmission.
I've seen several ICEVs turned into EVs and it's hard and labor intensive. Typically you end up losing the trunk space in addition to under hood space if you want anything more than ~20 mile range.
EVs are almost certain to end up costing less than a similar featured ICEV. They are simply so much simpler to build (once battery cell prices come down so more).
New tech costs a lot at first.
