Dude is about 200 years late to the party.
Musk's Other business has been here for a number of years, down in Boca Chica Village.
Still Texas has been one of the less friendly states in terms of Tesla, itself. There are plenty of entrenched moneyed, politically connected individuals that are actively belligerent towards Tesla. It'll be interesting to see if Musk is able to leverage a potential factory to overcome that with regard to the dealership rent-seeking laws here. I'd guess he'll have slightly better luck on that working out in Oklahoma instead, but maybe.
