There are a TOTAL of something like 16,000 install charging units in the US...
Not counting receptacles in most garages, for charging as you sleep.
So, while you are driving 600 miles, your plan is to what? Pull into a strangers garage to plug in?
Sorry folks, the infrastructure is NOT there for electric and isn’t going to be there anytime soon, even if they solve the pragmatic charging issues.
Its a niche vehicle option for commuters, nothing more.. and won’t be for a good while.
