Consider also it’s unusual for people to own cars for even 10+ years currently, for reasons that apply just as readily to electric or autonomous vehicles.
People want the latest and greatest. Many value the warranties they get with new vehicles. Over 30 years the odds of a vehicle being stolen or involved in an accident and being written off are also pretty high.
High mileage Tesla's show that the batteries last somewhere between 300,000 and 500,000 miles. Which is 25 to 40 years based on the median number of miles people drive per year.
> People want the latest and greatest.
Lot of people just want an affordable way to get from point A to B with a minimum of hassle and expense. The game changer with electric is if the batteries and motors last 25 to 40 years then the rest of the car needs to match that.
Appears though that electric cars are likely to be far more durable than gasoline powered cars and cheaper. In ten years a EV will probably cost 80% what a gasoline powered car would and will last 30 years not 15. Cost of ownership over the life of the car would then be 40% of a gasoline car is today. Less considering maintenance and fuel.
