Only couple of times per year I drive those kind of distances myself, but I’d say the main benefit comes for “derating”. In other words, you can buy a 900 mile range car, and can travel 400 miles in Lapland winter (batteries don’t like cold, and self heating uses battery capacity). So you can drive to a place ~150miles away and back without thinking about destination charging, plus some reserve. This system would also last longer since you’re not forced a full charge cycle every day -> less aging.

Surely not an issue if you can have multiple cars. One can just have a diesel car for longer trips and have a small electric city car for everyday trips.

But why would you need to fully charge? What matters is charging enough in a day to cover your daily needs.

Replacing bus drivers with computers won't make them any more attractive as workspaces. There's a reason musicians don't actually like touring.

Sounds great. Sort of like a train, except with more traffic, no bathroom, more sudden acceleration and motion sickness, and no space to stand up and walk around.

A fully autonomous car charging robot would be a solution for that now.

Fall asleep in your van, car recharges every 300 miles via robot, 3 days later you are on the other coast.

Truly autonomous cars will go on strike and tell you meatbags to take a hike!

Same applies to EVs.
