It would be quite ironic if hydrogen vehicles ended up beating electric. Though it seems sort of silly given that hydrogen must be converted into electricity, but who knows.

I would actually be curious to know if using an electric drive-train in a semi truck with a battery + diesel generator attached to it would be more efficient then a traditional truck anyways
I'm guessing that if you have a fleet, then a hybrid fleet makes more sense than hybrid vehicles in your fleet. Use the BEV for the tasks they are good at, and slowly edge out the diesel trucks as the BEV tech improves.
