Idiot Driving Early Warning System™

We have all seen how people tend to drive erratically as they talk on their cell phone yet nobody ever thinks that they do it. Therefore, the early warning system can monitor how the driver is manuvering the car and alert him in the event that he starts driving like an idiot.

Sometimes a motorist starts out doing a good job driving while being on the phone but he can also get so wrapped up into the conversation that he isn't even aware that he is disrupting the flow of traffic. And of course he is also oblivious to the dirty looks and angry gestures as people try to figure out how to get around him without getting into an accident.
