So basically, this part of your argument is that while hydrogen provides no perceivable benefit over electricity at this point in time, it will in the future because huydrogen technology will improve. You seem to be assuming that battery technology is tapped out, and that is simply not the case. Battery-powered electric vehicles travel significantly farther now than they did 20 and even 10 years ago. The fervour with which this type of technology is being pursues suggests that there is ample room to improve this even more.

I don't think that this is that big a problem. If it gets to that, a service station merely needs to calculate how many batteries it can distribute in the alloted 3.5 hour recharging period. how many patrons does an average refueling station service each hour? I doubt it would be anywhere near 100 as a mean number. If that were the case, how much space would be needed to store/charge 300–400 batteries? Is it really so excessive that this would cause problems for roadside service stations? I doubt it.
