friend of mine has lifetime free charging on his tesla at supercharger stations, so he never charges at home.
He charges it while he goes to starbucks.
The problem is that the model 3 is selling so well that his stations are going to be overfull a lot of the time soon
It won’t be free once larger numbers use those charging stations. Energy costs the same, no matter the source. Starbuck’s electric meter spins fast while they charge.
