All your movements can be monitored. Accidentally park near a crime scene last week? They can unilaterally disable your engine until the police have had a chance to interrogate and clear you. Not scary enough? Envision your own nightmare, perhaps starting with a crook driving behind you and forcing your car to a dead stop, having broken the communications protocol. I think the potential downside risks well outweigh the known benefits. To paraphrase Inspector Renault, it's the paranoid in me...
