And since the Teslas are self driving, they can just roam the public roads while people work, an endless TS (Tesla Stream) cycling between two superchargers.
Have a Manager Booth halfway between the two charging stations for checkins, in addition to video calls. Biobreaks (exercise, waste removal, nutrition ingestion) can happen during charging if the Teslas remain unmodified.
I just realized that the Tesla could eject the worker a couple miles before the charging station, calculating the workout and charge duration so that the employee would have to run at the correct rate to retrieve their car before it was done charging. The vehicle could self clean while empty on the way to the charging station.
I fully expected to see this in SF eventually. Wifi equipped buses set up like coffee shops that drive around SF all day. Cheaper than commercial real estate, at the time. I'm sure COVID has changed the calculus considerably.
They do this with billboards. It's somehow cost effective to have a big truck that is nothing but a rolling billboard drive around the city all day. By definition that means that it's cheaper or somehow better than a fixed billboard on real estate.
