Progressive has a rather creepy yet potentially money-saving way to save on car insurance called MyRate, WalletPop reports.

You rent a device that plugs into your car and tracks the length and frequency of your trips and the time of day you hit the road, as well as “jackrabbit” starts and panic braking. Depending on how well you score based on the company’s risk criteria, you’re eligible for a discount, apparently on a sliding scale.

How much would this sort of overbearing surveillance need to save you on your premium to be worth donning the electronic leash?
