I agree completely with this statement, but I think OP is giving up the car because he feels he was badly treated by Tesla's customer service, not because of the monetary value of supercharging. I think that's a lot more defensible than saying that he's giving up the car for financial reasons. If it really did take three months to recognize the change of ownership, then I guess that's the way it goes, but given how fast the Tesla app is generally updated with new cars, I find it hard to believe that was all. He also said a customer service rep told him he would get free supercharging, so there is at least a little culpability there. Either way, OP felt badly treated, whether correctly or not. My main point is that logic and feelings both enter into almost all decisions. Furthermore I think that recognizing (and accepting) that makes us better able to make rational decisions.
