Maybe this average is a result of accidents after a certain age. Almost any accident in a 15 year old car will cost more than the vehicle to fix professionally. I was surprised by the number though (which, to be fair, they didn't actually list).
The battery is the most costly part of an EV but battery prices are falling rapidly. The rest of an EV is simpler and has fewer moving parts than a gas car and will probably last longer.
When I'm in CA, people in parking lots often strike up conversations about the car like it's a classic and make offers to buy it. Police never take any interest in me since it's so common for people to drive old cars in a place they continue working just fine. The culture is completely different, I often wonder how much of it is due to the road salt alone.
It's also racial. I drove with a cracked windshield for almost a year when I was at University of Cincinnati. A black friend was amazed and said if he did that he'd get pulled over within days.
I suggest a great North-south car swap, where one side mitigates the climate damage caused by the other.
