I got the same treatment you got at Mercedes when my Model 3 shit the bed early last year. Inverter malfunction blew the pyro fuse, and I had to get towed to the Tesla service center across town. They profusely apologized that they had no loaners at the time, but would get me one as soon as possible.

They gave me free Uber credits for the week it took them to round up a loaner, which I drove for the next two weeks while they waited to get a good replacement inverter (the first one they got also went bad during their testing).
