And that, in turn, will be much smaller, because just like I've had a box fan for 15 years with no maintenance, so this superior technology will put parts suppliers and mechanics in trouble.
You write as if you believe a competitively priced, million mile ICE passenger car is somehow, an engineering impossibility.
Why aren't they made? Those answers depend on who you ask. Don't ask me to answer that question. Unless you want to wear a tinfoil hat and go down a rabbit hole. No. The answer is simple: Because people are impractical, wasteful, stupid, short-sighted and get tired of old things and want shiny new things for no good reason other than boredom and the desire to impress others.
The "superior technology" million mile EV will be purposely engineered to have a service life and fail. Maybe not the motor or batteries. But other critical parts of it will. And compared to an ICE, those 'other' parts will have a staggering cost. And after the car is ten years old or so, cost more than the value of the car. Because most consumers don't want their cars to last forever.
Auto parts manufacturers, and everything connected to them will NOT be set up to fail. In the end, we will all end up buying parts, paying mechanics, and spending money maintaining our EV's just like our ICE's.
Except worse. Oh, and all that power you're raving about. That will be influenced by insurance companies, Federal, and state laws . Just like ICE's.
