Ford's been working on a vehicle-to-vehicle communication system that has the potential to reduce a large number of accidents: up to 81 percent of them according to the National Highway Traffic Safety Administration. The system is called V2V. How it works is actually quite interesting: It makes use of an FCC-secured Wi-Fi signal through which vehicles can communicate with each other – a smarter collision avoidance alarm, if you will. When it looks like two or more vehicles are in danger of colliding, an alert is sounded in “an aggressive tone” and a strip of red LEDs atop the dashboard begins to flash. Using V2V, drivers would be warned if a car is approaching a red light too quickly, or be made aware of another vehicle’s presence when their vision is obscured. Ford also aims to provide the most efficient route information and lane-passing assistance. Clever stuff, but it can only be useful if all cars have the technology, because V2V won't be able to see vehicles that don't have a compatible set-up. That doesn't make V2V useless, it just means it will take a number of years before it or a similar system see the widespread implementation required to make a significant impact on accident statistics.
