As others have pointed out, the driver has to rest. The truck does not. It's an expensive piece of capital equipment that you want to keep on the road at all times until it needs maintenance. This is a good example of where swappable battery packs would actually be useful. The extra weight cost of making it swappable is much smaller as a percentage than it would be for a car, and shipping companies that run regular routes could easily have their own facilities to handle such things.
