The goal of self-driving cars is that they don't want you to own a car. They want robo-taxis that will drive people around, inside a 10-minute or 15-minute radius. Some cities have already introduced 15-minute zones, where people are allowed to visit only places that are within 15 minutes of driving from their home. That will shrink to 10 minutes.
The final goal is total lockdown, where people live their entire life within a 10-minute radius. They won't own homes or cars, they will be allowed to live as long as they are useful. So, electric car radius of 400 km is not a problem, since they are preparing us to live in a much smaller area.
Driving for fun? There won't be any such thing. Except..... if you're part of the elite. Then you'll have access to everything and travel everywhere.
