Within the last six months, I heard about two local police chases, with one being right down the road from my residence just last night. I see reports that GM OnStar will permit the police to shut down vehicles with the installed system at will. Anyone know of the validity of this report? Also, how would such a system work if this was implemented? To me, this seems like a double-edged sword. The best solution I saw so far is for the police to fire an attachable GPS device to the fleeing car and back off to prevent civilian casualties and property damages.
