If we try to overlay the EV network on the existing ICE model, yeah, charging will be difficult. But if we rethink the whole ordeal, it becomes much simpler, and in fact, I think once EVs become dominant, you'll see fewer mom and pop charging station than you see gas stations, not because it will be more expensive and difficult to run, but because the need just won't be there.

The majority of charging will be done at home, or maybe at work (I can see EV charging parking lots becoming a benefit). Long haul trips, depending on conditions, could be charged overnight at hotels, or quick-charged at restaurants.

Cross-country EV trips are already viable, although they require some planning up front.

And yes, quick charging produces more load on the grid than fueling up at the pump, but again, the majority of charging won't be done at a quick charger. It will be done cheaply, at home, at night.
