There’s a company doing this already. Giant battery sits behind the cab. They drive up, unplug it like a LEGO with a huge robot arm, plunk in a new one and good to go.

I think an automated battery swap system would work best for OTR trucking.

Yes, that and other commercial vehicles that put on a lot of miles in a day, every day.

Not to mention, most of these trucks are very standardized in their dimensions and parts already. This is probably the biggest thing that will hurt small vehicles is picking a subset of standardized dimensions that will fit multiple models.
