Here in Silicon Valley, the vast majority of urban charging stations are 6-7kW (and so are the home systems I know) . And the superchargers are either Tesla only or extremely rare.
If you drive I5 to LA or so, there are super charging stations on the way that allow one to plan a very safe and quick trip.
I have "hacked" my car's gas-based generator to -for long trips- keep the battery at 75%, and stop every 120 miles or so to quickly top off the little gas tank.
The charging network was the most clever thing Tesla did to own this market which they did for a long time. They started off in the cities, then one in the middle between, then 1/4 and so on. And the car sales followed that expansion area by areal. They were way ahead the rest for a long time. An aquaintance of mine "got it". Their family operated a quite profitable gas station with a cafe, fastfood and motel facitilites, and he managed to convince Tesla to put one of their faciltities on his ground at a very early stage. These days, the've moved the road, and the charger will be what will be keeping him in business. Without it, he'll be bust.
With the car culture, vast number of cars and the distances in the US, I'm rather convinced you'll need upgrades of the distribution grid, energy production and then some, to make a complete transition to EV - if that's what people eventually wants.
No chance, we've had 35% EV and 98% EV registration (new cars, 2026) with 6-7kW charging along the roads. Zero chance. As mentioned before, I got 3 charging points within 1/2 a mile, and another 20 miles from here. One gas station shut down, another on the verge. No chargers, and they'll be gone.
A couple of new EU rules (tyres needs less wear, and increased weight for drivers licence classes) will have an impact, the latter because it opens the EV market for another driver segment. Towing capacit was the previous issue - quite a few wants/needs good towing capabilities, and some businesses have waited years to go EV as they weren't made to pull enough.
There are 4 problems with the expansion of EV:
1: Energy production and the AI/Sky servers plants which sucks the life out of everything.
2: Upgrading the distribution grid for robustness, to handle commercial and home charging, and establishing a commercial high capacity charging network.
3: Weight and tyre/road wear (I'm a sinner, I prefer Diesel SUV due to a.o pt 4)
4: Wherever relevant - contigency and e.g. roads which closes due to bad weather and results in being stuck in a car for 12, 24 or 36 hours.
If neither of these points are issues wherever people are, EV would be the better option just about anywhere.
...as long as the owners don't give a f**k about own and other's privacy and information security.
