We already have one. It's in the Ammu-nation. It's called a baseball bat.
To elaborate: What roleplay comes from clicking a button and having a vehicle start smoking? All that accomplishes is the person coming back to their vehicle, saying "aw, fuck," repairing it, and being on their way. There's no chance of getting caught, facing retribution for your actions, and thus getting roleplay from the whole thing. You just mess about in the engine and fuck off. This would provide no RP value to the server whatsoever.
