I had a fella try to car jack me once and all I did was stomp on the gas and drove away with my driver side door flopping open. I was lucky, simple as that. I did not have my door locked and I was more interested in finding something on the radio that resembled music than paying attention to my surroundings. I got lucky but luck is not a plan. Personally I work on my awreness skills more than my shooting skills when it somes to driving.
