Maybe the answer is to stay in your vehicle and calmly display a weapon?
I’m behind the wheel of a 4000 pound weapon
The 17 shot 2 pounder in my console keeps me from having to use the bigger one
I have used that tactic to good effect a quarter century ago when wife and I got off the interstate at night on the wrong exit in Jacksonville Fl.
I don’t think that is the answer.
If you display a weapon, be prepared to use it!
Better to run them over if you feel that your life is threatened!
