Police Can Disable New Cars on Demand

General Motors plans to equip 1.7 million of its 2009 models with a system that allows OnStar operators to cut engine power in the car if the police request it. The system was demonstrated in Washington, D.C. today.

GM's OnStar system already contains built-in GPS tracking that would allow police to find any OnStar-equipped vehicle. With the new technology, if the police request it, an OnStar operator will inform the occupants of the vehicle and then cut power.
