New tech can let your car talk to other vehicles

In near future, a car could potentially talk to other cars around it, thanks to a latest technology under development that could have great impact on road safety.

Carmaker Ford demonstrated Vehicle-to-Vehicle Communication (V2V) at the recently concluded CES 2014 event in Las Vegas.

Although, V2V -based on Wi-Fi, has been in development for a number of years but Ford's tech, dubbed "Where I Am," simply broadcasts a car's position, direction, speed, and other bits of situational information ten times per second to any other car close enough to listen, The Verge reports.

The tech provides a complete picture of the traffic around a car that can potentially help avoid car crashes by information related to scenarios when a driver runs a red light at an intersection, which could in turn trigger an alarm.

The report added Ford saying that real V2V signals would be "signed" by a trusted authority, not unlike an SSL certificate on the internet, so that cars would know to reject incorrectly signed data.

The data about surrounding cars is anonymous without any identifying information like a VIN, and Ford said that the MAC addresses cycle every five minutes, which means that a user would not be able to identify the source of a signal for more than a few minutes at a time.
