The issue here isn't really a bug, it's just trolls being trolls. Being able to stick friendly vehicles with C5/C4/dynamite (Jeep Stuff) has been a staple of the Battlefield community, and it has always been a double-edged sword. Some players will plaster the front of a vehicle in Jeep Stuff to ram enemy tanks and blow them up instantly, so there needs to be a way to counter that effectively. There's also players that use Jeep Stuff to launch vehicles across the map or into impossible locations, which is all in good fun. However there has also always been players that would covertly plaster their teammate's vehicle in explosives just to grief the driver.
I've had this done to myself a few times, and there is nothing more annoying than being on a roll in heavy armor, keeping enemy vehicles shut out and fending off their AT attempts with hardly a scratch, only to die in one hit when you shoot down a Lis rocket just a little bit too close. 10 points for a rocket destroy, but 4+ dead teammates, all because some chump didn't like that the TOR wasn't right up on the objective with no cover and surrounded by AT.
