I think ICE-car technology has been taken very close to it’s limits. It’s similar to where we are with digital computing, the end is in sight for both technologies.
In terms of acceleration, assisted driving and overall day-to-day transportation use, EV’s have it all over ICE cars in all categories except long-range trips.
