Citation needed. EV chargers are actually pretty common, at least in the UK. Jump in any EV and the satnav will show you all the chargers nearby and they're basically everywhere. Sure perhaps 7kw and not 150kw+ but even grocery stores have many of those 150+ now, even if they don't have their own petrol station.

Yes, I'm sure it depends on the locale. Sorry for not specifying. In the US, particularly more rural areas, it's difficult because we have such vast distances. On a long trip, there aren't enough DC fast charger OR level 2 chargers, the ones that are there are often broken and/or in use, and it is quite the adventure to plot a longer trip.
