Sure, but you're missing the point that you yourself just made: "are going to start", as in, they haven't yet. Most people are not going to buy an EV today without a reasonable charging solution, banking on the idea that situation will fix itself at some point in the hopefully-not-to-distant future.

Yeah, it's always been a chicken-and-egg transition problem. There's always a least convenient link in the chain. Hence all sorts of schemes to nudge people / subsidize early adopters so the cycle of "we don't need to solve charging because nobody has EVs"/"we can't have an EV because there's no charging" is broken.

Hence why I think it will expand outward from urban centres, motivated by e.g. ULEZ requirements.

Hawaii already has this rule for what it's worth. The issue there is that they have so many EV's on the road that these chargers are always in use and have lines (and aren't really that fast to begin with). Having experienced that, I still wouldn't get an EV without a guaranteed place to charge at home.
