tape razor blades under door handle when you leave, put syringe in driver seat (when you have been mysteriously stuck by a syringe..what are you going to do :roll: drop what you are doing and run like a fucker to the nearest hospital)

if you want to get really seriuos..mix equall parts of amonia and bleach in a container and leave that in your car over night...you should find the perp passed out..possibly dead..in the driverseat (disclaimer: dont do this)
When the cops asked why you left a mustard gas bomb in your car...tell them you were cleaning your dash and must of forgot the solution in the car (disclaimer:do not clean your dash with bleach and ammonia solution :lol: )

Or you can just practice your second amendment rights
