When fast charging takes over an hour (Chevy bolt fast charges at 50kw, less in actual use), you do really have to plan trips.

A majority of EV owners don't have L2 charging at home, and a short 30 mile weekend trip (60 both ways) is more than a L1 charger can replenish overnight. Way more if you use AC or drive when in cold weather.

I can easily drive more than I can daily charge with errands or driving the kids to class/camp.

If you use 230 V instead of 110 V, and three-phase instead of split-phase, the lowest charging tier becomes 3 kW (instead of 110 V @ 15 A = something like 1.5 kW), and pretty much anyone who has a car hole can easily install a 11 or 22 kW charger. This might make a pretty big difference in the end for all the house-owning people.

The American decision to use intentionally limited, low-tier electricity grids as a cudgel to enforce zoning shows yet another facet of externalities.

It's easy if you have the $$$. Personally, I don't want to spend a few thousand to buy a charger and have an electrician run a 240v plug to my detached garage.

On my old house, there wasn't enough capacity to add another 240v breaker.
