Back when I worked for a major bank we'd distribute firmware to remote branches via usb for updating ATMs that still had dial up modems. Numerous safeguards existed and it never was a problem.
The car has connectivity. If a usb update is attempted the car can phone home to ensure the update is valid before proceeding. Any evidence of tampering would cause it to abort and fail.
Distributing files via usb internally in a company = no problem.
Distributing FW that controls a Model S = hack risk and/or reverse engineering risk.
So, you're also suggesting that if an update was via usb then it could not take place unless the car had a 3G signal? The point up-thread was that people needed a usb update as in some circumstances (such as your garages etc) they couldn't get a 3G signal.
I'll still bet you a cup-holder it doesn't happen.
