The Lemur Autovision is a key fob that records and displays a driver's habits, including miles driven, average speed and the frequency of braking. With a base transmitter hooking into the car's on-board diagnostics port, all information is fed directly (and accurately) from your car's computer to the LCD dongle itself. Priced at $80, it's either a way to spy on your kids or a convenient manner to track and curb your own bad driving. You decide.
