I don't even have EV yet, but just installed a Nema 14-50 socket today when an electrician was coming to do some work on the breaker box for some problem we were having. He was able to do it for $50 extra (not including the materials, which was $150 or so)
I figured I'm going Tesla after wife's lease is up and in-laws (who's already ordered one) can use it when they come over.
