This is true enough, but it's advice of the same form as "Don't buy a pickup if you live in NYC and only have street parking". It's a valid exploration of the solution space but not a fundamental indictment of flatbed technology.

"We shouldn't say EVs are good because they aren't good in all ways" is... kind of a dumb point. And in particular the specific point you tried to make is, as I pointed out, actually incorrect for the bulk of actual owners.
