I'll just run down a couple of everyday cases in which tampering with the car could have a significant impact: - Company car, car programmed to track employees trips without their knowledge - Company or rental car, interfaced with immobilizer so it shuts down if it exits the designated area (for example heading across a border). Results in a night spent in the boonies and lawsuit. Optionally the people spending the night in the boonies also get mugged, possibly violently, or become coyote snacks. - Jealous or control freak husband/wife makes changes on car to track SO or to cause trouble under certain circumstances. The plot backfires and results in some injury to a couple in the back seat of the car. - Teenager tinkers with parent's car, induces unwanted bug, car crashes later as a result, perhaps by surprising the driver with something as innocuous as suddenly appearing strange instrument displays. - Parents have a mechanic modify the car so it is slow when teenager child drives it, to avoid further speeding. Car is rear ended in traffic as a result. This is just like that, off of my head. I think that tampering with a car's systems should be illegal, and doing so should require a license of some sort, and the tampering be entered into the car's paperwork by law. Same as modifications to a car's mechanics or exterior lights must be and are. I also think that there should be some kind of special license for cars modded for racing, and that that should be made obvious from the outside of the car too (different colored license plates etc). I am sure that some companies will provide a firewall for cars, the problem is not the firewall it is the system design, which is unprotected yet proprietary. This results in the impossibility of testing for tampering by arbitrary third parties, legitimate or not. -- Peter -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
