The Lemur Autovision key fob is a device designed to keep track of exactly how good/or bad of a driver you are. The device has a base transmitter, which you hook up, to your cars diagnostics port. That transmitter then sends back information to an LCD dongle about how far you’ve traveled, what your average speed is, and how often you brake. While those stats will definitely vary depending on where you’re doing your driving, it’s still an interesting idea. Pick one up now for around $80. [via coolest-gadgets]
