The US government wants carmakers to put a device in your car that will stop you from going over the speed limit.
Citing the number of deaths from speeding cars, the National Transportation Safety Board has recommended the auto makers be forced to install devices on cars that will at first beep to alert you that you're going over the speed limit. Then, if you ignore the beeps, the car will automatically slow your car down.
The speed-limiting devices use telematics. By tracking you through GPS, they compare your speed to a national database for each road. Federal data shows more than 20,000 deaths on our roads in the first half of the year. This new effort is predicted to save tens of thousands of lives each year.
