Will Tesla become The Standard everyone else has to comply with, and if so will they nail the other EV’s a fee for using of Tesla chargers?
What effect on innovation by other companies?
My own hope is that they fight to the death and none survive!
Of course the Tesla Supercharger network is only available for Teslas—why should Tesla open it to others? In any event, in the USA alone there are several competing (but inferior) networks of charging infrastructure, and Mercedes-Benz are building their own global charging network.
You can hope all you want for EVs to fail, but they’re the future, whether you like it or not.
