How about your car says in a middle aged women's nice and calm voice but highly amplified. Kinda like those messages in Harry Potter than read themselves in the voice of whoever wrote it. I would choose my old American History teacher for the role.

"Hello, I have come to find that you would like to steal this car, but I cannot let you. For I have promised to be faithful and only let my owner drive me, and you are definitely not my owner.

Thank you for not stealing me and have a nice day or night, I can't tell which it is since my day/night sensor broke.

(Pause 5 seconds) You know what, I really should gett that fixed, I need find some way of telling my owner, I think he would gladly replace my sensor as he is a very nice guy. Could you tell him? I'm sure he is not far from here by now?" (Car waits for reply)
Dr.Hashman Reviewed by Dr.Hashman on . Someone needs to develope this. Ok. We all know car alarms suck. Who actually pays attention when they hear "BEEP BEEP REER REER WAA WAA REE REE BOOP BOOP..." So this is what I propose. We start making car alarms that scream out curse words. If you were walking down the street and you heard, "GET AWAY FROM MY F*CKING TRUCK YOU STUPID, C*CKSUCKER MOTHER F*CKING C***," I think people will turn around and look. Plus, I think this alarm would sell so well, the company could agree to any tickets one might recieve for offending Rating: 5
