My alarm keyfob went off on my wife's car one time, I had enough time to go out and confront the family that was carelessly letting thier kids fling the doors open to get out. My alrm has a 1 mile range. I sprinted out, caught them and started going columbo on thier azzez. They tried to deny it I lined up the litlle fat kids door with the ding and collected thier insurance info promptly. I chewed them out pretty good in the process about their careless actions. I bet money they will never do that crap again!
