EVs without supercharger access are strict city cars.
The electrify america network sucks, non tesla range is mostly bad (with a small number of exceptions). Even with decent range, lack of supercharger access makes the car a non-starter.
I think Tesla's advantage here remains huge, I think legacy car companies are in trouble (and this is even ignoring their inability to write or ship software). The dealership model of legacy car companies will also be a big problem for them and will continue to hold them back.
That said, I think ultimately forcing the EV switch makes sense and with something like supercharging in place is viable. Battery capacity will continue to improve, charging rates will continue to improve. Pushing this shift makes sense.
It just might be that legacy car companies are too dumb to do it properly and will cede a lot of the market to Tesla (and maybe Apple).
