Tbh, it sounds fair enough since this idea can solve this problem, and not benefit one team.
From my point of view the current average resistance to gunfire that vehicles have is already fair. Just the fact that its impossible to pop-up someone's tyres with an average gun, brings already a huge advantage to the vehicles' bullet resistance. Other than that special armored vehicles exist for a reason, in case you are about to drive through a heist, or any other event that would expose you to firing bullets, just pick the right vehicle instead of a supercar like cheetah.Going Negative
