No way! It was a helpful suggestion. I forwarded it to the dealer who asked Tesla if that was a possibility. The (filtered) response was that it was only possible in two scenarios:
1) The trucker is a skilled hacker (read: can follow a Youtube how-to) and put it into dev mode.
2) The previous owner had it in dev mode and the trucker inadvertently found transport mode and engaged it.
They couldn't confirm it, however, because in its current state they can only get limited information. So it wasn't ruled out!
They say I'll have to wait until it arrives and do a reset. Just really odd timing that something "so rare" happens just as its being picked up.
The good news is, the trucking company contacted me today saying they're on schedule and I should have it Friday! YAY!
