In vehicle racing communities it becomes necessary to prevent people 'boosting' themselves to cheat. In some places this is by insisting a classic avatar with zero scripts, or unwieldy speed monitoring systems to highlight boosted behaviour.
The cheaters use a HUD or other attachment to 'push' the vehicle they are sat on (and they can push it, because they own it).
If a script inside the vehicle could be able to detect these pushes, it could react from within against the cheating.
Or if there was a way to set a vehicles status that it does not react to pushes, even by its owner?
extra note : this is not about 'grabbing' your vehicle to give it a push - that can already be prevented with llSetStatus tools.
