I have a tough time believing this.

1. You're telling me you had a vehicle up on a lift, by its wheels, and there was no chuck or gates to stop the vehicle from rolling?

2. I'm assuming you're saying the customer used "Summon" to remotely move the car. a. Summon will immediately stop the car if it detects even the slightest bump. b. Summon will immediately stop the car if it detects the wheels are off the ground, which is relevant because: c. Summon moves the vehicle at like 3mph, so even if the vehicle was AWD, since most of the weight (which is distributed throughout the vehicle) is still over the lift, there is definately not enough momentum to push it off the lift. d. I am fairly doubtful the auto insurance would not cover this, especially if the guy had comprehensive insurance.

Chucks are there to stop a vehicle from accidentally rolling or pushed away. They aren't designed to stop an electric vehicle (that has tons of low rpm torque) from being purposefully driven off.

Tesla's Summon mode has very low torque limits, it will barely make it up a slightly slanted driveway.

Like I said, Summon will immediately stop the car if it detects even the slightest bump.

Me too. Doesn't make any sense.
