The place where BEVs have yet to prove themselves is when energy density is absolutely critical. Long distance transport of any sort (air, sea, train, semi) is really the next places for them.
Semi is a maybe at this point. Train MIGHT make sense, but, IMO it'll probably make the most sense as an energy capture/getting the train up to cruising speed aid rather than as the sole power source. Heck, for train, it'd make sense to instead electrify the rail system. Sea seems unreachable (Sails make more sense at this point which is sort of wild). Air, IDK, there are definitely projects to hit it, but I don't see a large commercial plane doing BEV. Perhaps for smaller regional hops it'll make sense.

Europe could pull it off due to its density, but the stretches of American highway which would benefit the most from it, would be a huge challenge.
But note, they do actually have batteries, similar to ICE serial hybrids.
They key thing of course, is that building lots of batteries is not a 'problem', and it's lack of being a problem is exactly why BEVs are better than fuel-cell hydrogen cars for basically everything, except maybe long distance air transport.
