Something is becoming more common...car alarms. When I hear a car alarm, I don't look out the window until the car alarm has been going for more than 5 minutes.
When I hear a car alarm, I don't think to myself..."Hey...I think someone's car is getting stolen." I think to myself "My God! How annoying!"
I don't like car alarms. If you are going to spend the money on a car alarm, get a freaking low-jack.
