I was sort of in this situation once. I witnessed an act of vandalism and was following the ute’s in my car while on the phone with police dispatch. It escalated when one of them threw a rock at me ad broke my windshield. I turned down a street which turned out to be dead end. A small gang of ferals joined the party and were trying to get into my car. I could see the police lights on the way so I didn’t do anything but sit there.
It’s amazing how quickly the party stopped when everyone had little red dots pointed at their center mass. Several went to jail that night. The police barely asked me my name.
Put the car in reverse, crank the wheel all the way to the left... floorboard the car. Out of control backwards donuts will clear a crowd. Guaranteed.
