I don't think these are terribly accurate.....
No, cars will just last longer. With the thermal management of the battery, except in extreme cases, there isn't that much degradation that you'd have to get a new battery after 100,000 miles. Maybe cars won't be disposable anymore....that's a good thing.Basically we're seeing the end of used cars. If nobody can afford a new battery, they'll always have to buy a new car.
