Cars with these systems or with on-board navigation systems also have global position (or GPS) systems installed. GPS uses satellites to assess the exact location of a car.
Several car companies are now working on systems that will allow cars to communicate directly with one another, passing information back-and-forth about each vehicle's position and speed.
Data produced by sensors attached to the stability control and anti-lock-brake systems could instantly relay data about when a car is stopping - or not stopping - instantly warning other cars about potential hazards ahead.
