[citation][nom]Razor512[/nom]after you give them your wallet and stuff, when they are walking away, pull out your gun and shoot them in the back them take everything they have on them and drive away[/citation]I hope you're joking, even though that would make it a poor joke without a punchline. [citation][nom]Razor512[/nom]anyway onstar is good for situations like this but this feature can be prevented if the criminal has a cellphone jammer in the car with them[/citation]If you had a cell jammer, yes you could probably prevent them from disabling the gas pedal. But the GPS function is satellite-based. You'd need a higher end jammer capable of jamming both, or a second jammer. They're illegal, though you probably wouldn't care if you were stealing a car. However, someone stealing a vehicle at gunpoint with a sawed-off shotgun probably isn't smart enough to carry such a device.[citation][nom]Razor512[/nom]a better solution would be also have a special rf receiver and a device where the car owner can give police the code to also shut off the car when in range, great backup if the criminal has a cellphone jammer.[/citation]They don't want to shut the car off, as that would greatly reduce their ability to steer or use the brakes, almost guaranteeing an accident. They disable the accelerator (fly by wire). Anyway, what makes you think that any RF device they choose wouldn't be susceptible to jamming? Satellite and cellular links operate at a variety of radio frequencies, what would make your "special RF reciever" immune to a future jammer? Smart criminals will always find a way around it. This is designed to deal with your more common crooks, the kind that won't have a jammer in their pocket.
