Well, the evil plan was actually to get about four of them, and rig them with HE grenades. If my vehicle is being pursued at high speeds, flip the switch to turn all four of them on, give them their target (that command kills their wireless) and have them all just go full on at the thing chasing me, coming out the rear of my vehicle. Result is that the guy behind us gets a surprise - specifically 4 HE grenades on a ramming test, where he is, ideally, an unaware driver, thus dealing with those penalties, and he'd have to deal with four seperate ramming tests.
It really is however, one of those tricks that only ever works once.
