Detecing it is just partially useful, as you cant find the player who caused it.
I would constantly store the position and velocity of vehicles, and use a flag that indicates a valid respawn (via script or vehicle death). If position changed with the flag not set, the hack was probably used. Then just restore the old position and velocity, so the effect for the driver and the other players is at least reduced.
If the hack doesnt have much impact on the server, hackers might lose interest in it.
