It's not just a question of where the charging stations are, it's a matter of having them in conspicuous and convenient places. Everyone is comfortable driving locally and long distance because they know there will always be a gas station within a reliable distance that won't be a hassle to find.
As a non ev owner, I think I've seen charging stations here and there, but if you'd ask me how many there are nearby I'd probably guess maybe a couple dozen within a few mile radius as opposed to probably hundreds of gas stations. Whether or not I'm correct, this is probably the perception of the general public. If there would be charging stations that looked like gas stations on street corners and highway exits, that would probably change thing.
Also, I am sure plenty of people that mostly use their car for a local commute in a city that has charging stations, still won't buy an ev because maybe once or twice a year they want to take a road trip and feel they won't be able to.
