"drive away" is a kneejerk answer that covers only the rarest of occasions.
it is spouted by the brady bunch and their ilk as a manner of 'safely' getting out of a bad situation, problem is, it's almost never an accecptable saftey risk.
anytime your running from an attacker will put more innocent people in harms way then it is a bad idea to run.
simple esclation, guy gets out of his car, I get my hand ready to draw my gun and verbally challenge him to stop and leave.
guy does not heed warning then I challenge again and express intent to defend myself. If he gets a weapon, skip to number three.
guy makes continued aggressive actions and keeps coming, he gets the business end of a gunbarrel pointed at his head.
he keeps coming then he gets shot, he leaves then I call the cops and report his plate and vehicle description.
try to run in a busy intersection and you will wind up hurting an innocent person, if someone must be hurt, may it be the poor dumb bastard that it trying to hurt you.
