That’s not true. 500 mile range semi trucks are feasible with careful engineering. That’s long enough where drivers have to stop for regulator rest anyway. See: https://selenianboondocks.com/2017/11/tesla-semi-part-1/

More for lithium sulfur.

What are the chances of a Tesla megacharger exactly at the closest exit when you hit your 8 hour mark, and also not being used by any other trucks? Real life usage requires buffers.

This really isn’t a problem.

8 hour is the MAXIMUM you can legally drive at a time. 11 hours is the daily maximum driving time total. So as long as there’s a mega charger between your 3rd and 8th hour, you’re fine. Then charge overnight slower.

Lithium sulfur (or a smaller load) enables no need to charge during the day at all. Could go the full 11 hours driving each day and charge at mere Supercharger (or CCS) speeds overnight.
