How much is your privacy worth?

If you let Progressive monitor your driving they will offer you lower Insurance rates:

Usage-based insurance relies on a small monitor hooked up to the car’s diagnostic port. It calculates a driver’s risk by measuring miles driven, acceleration, braking, speed and possibly where the car is being driven using a GPS. This allows the insurer to forgo normal risk factors, such as age and driving record, in favor of real-world information about a person’s driving habits.
