Just in case the old ladies flipping you off after you clip them in the crosswalk isn't enough, State Farm has released the Driver Feedback App to rate just how poorly you drive. By measuring (and recording!) how hard you accelerate, brake and corner based on your iPhone's accelerometer and GPS location, the app is able to provide a detailed, mapped report of your driving habits and provide helpful driving tips (STOP HITTING PEDESTRIANS). It will even give you an overall score for each trip that you can try to beat (either high or low depending on how you're playing). Luckily, the app does not report any data back to State Farm so they won't automatically know about that hobo you "accidentally" ran down the other night.
