If car insurers want to make them an easy sell try solving a harder problem than just small discounts.  Register a car in the city of Detroit and your insurance rate goes up 200-300%.<p>How about a device that you can activate from your cell phone that not only tracks your car but actually shuts it down? People would be creeped out by tracking but if you can save 70% on your insurance and at the same time more likely save your car from the chop shops it would be a win for everyone.  Then have a private service that retrieves the cars so the police can work on more serious crimes.
