I suspect that battery hot-swapping will be practical for electric trucks. Charging them is really slow unless you use a dozen of cables. Parked time costs real money for them. Normal trucks unload, reload, and go back to the highway pretty soon, often with a different driver at the wheel.

Truck yards usually already have equipment for heavy lifting, and the batteries need not be tailored to the car aesthetics and space constraints. Also, a narrower industry has a better chance to come up with a common standard.
