> we could make EVs with the same form factor as today but with over a thousand miles of range. Not that we need that

I think this is the way to go. For most people (you can never please everyone) 1000 miles is enough to cover a full day car trip.

Then 8 hours of charge time while you sleep.

Charging while you sleep requires more distributed, lower power infrastructure compared to a 10 berth service station trying to juice cars in 5 minutes as seems to be commonly touted. I haven't run the numbers but juicing 10 cars in 5 minutes has to require significant electrical infrastructure!

Side bonus: never having to go to a service station.
