A device which insecure people waste money on because they are afraid their sacred, shiny cars will be stolen. Since about 99.9% of car alarms are false alarms, however, the owners eventually forget why they got the alarm in the first place, and get used to their cars crying wolf after a few occurrences.

Occasionally this will encourage angry neighbors to do whatever they can to put themselves and these useless devices out of their misery. This may include vandalizing the offending cars until they can disarm the screeching, honking, blaring whiners. Therefore, car alarms actually lead to more damage than good, and are one of the most foolish inventions in the history of mankind.
For the fiftieth time in two weeks, the car alarm went off triggered by a bird who perched itself on the trunk, which caused a neighbor to get a baton and whack the offending automobile until he was able to get to the alarm and break it in two. Five minutes later, as the commercial break arrived during the action thriller movie, the car owner came out. Suddenly he realized that the alarm he had originally came to stop was no longer blaring away. He then saw the damage to his precious luxury and fainted.

When you and your friends play tag by the use of car alarms in a large parking lot. By setting off the alarms of different cars the "it" player tries to track down the other members in the party. Upon coming physically touched by the "it" person the game cycles all over again just like regular tag.
Remember, a parking lot is a dangerous place. Soo watch out for traffic, and people who don't want you playing. Let's play some good 'ol Car Alarm Tag, now let's get it on!
