Were I the French bloke with the knife actuated seat, I'd have constipation from worrying about a false alarm while I was driving my own car! Around here, the problem is not stealing cars, but break-ins and stealing stereos. This is usually accomplished by prying on the dashboard with a big crowbar. I would think a good car security system would disable key functions (like the ignition or the distributor) while turning on lots of lights and horns. -- Lawrence Lile http://members.socket.net/~llile/index.html -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
