If you want to look at the limits of what physics seems to allow (cost practicality be damned), look at things like americansolarchallenge.org winners. They even have a multi-occupant-vehicle class nowadays.

The 2018 MOV winner (https://www.americansolarchallenge.org/the-competition/ameri... ) logged 1762 miles over 58.4 hours, or about 30mph average pace (with a 16.8kWh battery, but no external charging, just the ability to time-shift some energy).

That's with a vehicle that looks like this: https://www.youtube.com/watch?v=aE9gkYsR4TU
