Alarms are too hysterical. You brush by a car and the thing starts freaking out. Like the little boy who cried wolf. It's like shut the F up. They need to start making alarms that can assess the situation at hand. So if it gets bumped it can give a little 'excuse me cough', and then when the windows break then it starts crying murder. Then you might take the damn thing serious.

I say buy a gun. Put a couple .22's on the back dash. They'll get the message. I don't know what the law is in Mass, but in LA if you're getting car jacked you can shoot'em dead.
