Technology can predict dangerous driver error

Let's face it, almost all automobile crashes are caused by human error. But what if there were a way to predict driving mistakes right before they happen?

That's the promise of new technology under development by researchers at Cornell and Stanford universities. While many cars already have sensors and cameras that watch line markings and surrounding vehicles, this new system also uses cameras inside the car to monitor the driver.

Subtle movements of the head and body can indicate that a driver is about to turn or change lanes in the next few seconds. With that information, combined with data from sensors outside the car, computers can predict that a driver is going to make a dangerous move. Example: turning left in front of an oncoming car.
The driver could then be warned that he is about to cause a crash.
The system could also use GPS data to warn a driver that, say, the turn he's about to make is illegal at that time of day.
