I fear that we might instead have a time period where fundamental battery technology (or our ability to harness it) will not permit a retention of 75% of range over a 20-year period. It might be like the cars of the 50s though 80s which rarely made 250K miles without major engine service.
Cars used to have 5 digit odometers in miles and it was a noteworthy event to “roll one over”. Now, the worst crapbox you can buy will do 100K easily and many of the Japanese imports will do 300K miles with a few external accessories being changed along the way.
Of course, we could find ourselves in an apple-google situation where the cost of the cars themselves is reduced to a price point that a mass market can stomach, and the cars are "disposable". That thought makes me sad.
It also makes me sad, both from an ecological standpoint, but also from a financial standpoint. I see a lot of people making car payments that are $400+ for 72-month loans. (The average car loan length in 2019 was 69 months for a new car and perhaps an even more astonishing 65 months for used cars.)
Then, because they have a loan, they have to have expensive collision insurance and maybe even gap insurance. Then, because it's an expensive liability they see everyday, they feel like they have to take it to the dealership for repairs (to "protect their 'investment'"). Some people feel like they need to build a little house to protect it (which needs a curb cut and associated extra land usage), etc.
If it were more commonly accepted to drive a "millionaire next door" 15-year old Camry or CR-V, I think we could go easier on the world and on people (maybe except for people who work in the automotive new-car supply chain).
Until then, I can be happy that people buy so many new cars so often, because if they didn't do that, there wouldn't be any cheap used cars for me to buy and DIY-repair to avoid the shop rate and parts markup. :)
> The last two ICE cars I had, I bought them when they were 12 and 9 years old,
You're comparing technology that's had 100 years to develop, with the first iterations of EVs. You're right in that a current 2 year old EV likely has a much lower resale value than a 2 year old ICE vehicle. But remember that the Model S has been on sale for less time than the time between now and when this ban comes into place. Buying a 6 year old EV right now seems like a terrible idea, buying a 6 year old EV in 2035 will likely be a very different story.
