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.
