Right now, I'm sitting in a Target parking lot. I've positioned our car in a space so that I'm facing the front door. I'm in a well-lit area and I can see all around our vehicle. When my wife emerges from the store, all I have to do is crank it and punch it. I'll roll up and the passenger door will be right in front of her.
I'm minimizing her chance to encounter a purse snatcher. Our dog is in the back seat with a deep bark and sharp pointy teeth to minimize our interactions with car burglars, carjackers. It's the least I can do for the holidays.
