I've had someone try to get in my car while it was running ... I was in a QT with the car running (remote start) and the alarm of course was armed with the doors locked ... I came out with a six pack in hand and he was missing with the handle trying to get in ... at that point I then yelled out "What the Fuck do you think you're doing" he ran behind the building and off to who knows where. Even if he had got in the car the kill switch would killed the engine, alarm would be going off and some wonderful pezos would be making his ears bleed in pain. long story short ... Don’t fuck with my car
