Has anbody tried this shatterproof glass film. It seems like this would put a stop to most burglars. The only downside i can see is if you somehow became trappped in the car. Would they be able to cut the glass and then roll it down or something. Im just curious. I want to get gps for my car but im worried someone will rip it off.
