AI drivers should stop vehicle when tires are blown.
Currently they will keep driving towards their waypoint. This happens with either, one two three or four tires blown out.

Driving with one tire gone is ok, but it looks ridiculous when they keep on truckin without any tires at all in 3 kmh.

Realistic solution: They should just stop the vehicle when two or more tires are missing.

Wishful solution: would be for driver to pull off the road (if already off road, just stop) and everybody except gunner should jump out and make 360 security to defend the vehicle. {F21243}
