They’re only required to make parts for 10 years, and batteries don’t age well.
My current vehicle is 17 years old, has 270k on it, I expect to easily get another 10+ years and another 100k. Even then, I won’t get rid of it, just use it as a spare, so when I or any of my family/friends need a vehicle because there’s is down, it’s available. Our newest car is 7 years old, approaching 100k miles. I expect another 15-20 years out of it.
There are cars in my family that are 30 years old, still running, still getting 30 mpg. Yea, engines have been rebuilt, once, they aren’t pretty, paint is faded, chipping, etc. But they still work fine. Even have AC.
Ev’s are the ultimate in planned obsolescence. If we didn’t have cash for clunkers, lots more perfectly serviceable cars would still be on the road.
