The concept non-EV owners struggle with is that with an EV you don't normally go out of your way to charge it the way you do with an ICE. If you can charge at home, at work, at the grocery store, and at restaurants then why do you need a filling station? If you start your day at 100% because you charge at home then you don't need any of the other infrastructure unless you go on a road-trip.
The amount of charging infrastructure need is also based on both demand and use case. A grocery store or restaurant might opt for DC fast chargers because they know customers won't be around for more than 30 minutes, but an office park can use 3-6kw chargers because users are there for 8 hours a day. The EVSEs are smart too so you can balance output based on demand. Have two EVs plugged in, they both get 3kw. Just one can pull 6kw.
OK, maybe the goal should be to relax our assumption that recharging happens at the gas stations, and just spread the load to all the parking lots we can find. Then gas stations could just have the quick-charge versions for more $$.
> That would be useful at a hotel or workplace, but it won't replace a gas station.
Also useful at any sit down restaurant (even fast food). (which although self driving makes driving while eating safer, was a horrible practice to begin with)
Addon; Tracked long trips we took in the SE last year against the Tesla charger map; There was always a super charger within 1 mile of where we stopped for food, were stopped for about an hour, etc. And some in our group also needed bio breaks every hour and a half; aka < 150 miles.
