One Reason Why U.S. Vehicle Communications (Machine to Machine) Market HAS to Grow

The U.S.  Department of Transportation (specifically the U.S. NHTSA) is preparing regulatory proposals to make vehicle-to-vehicle communications (part of the broader "machine to machine" market) compulsory, to prevent crashes, reduce traffic congestion and to save fuel.

The U.S. Department of Transportation's (DOT) National Highway Traffic Safety Administration believes vehicle-to-vehicle communication technology for light vehicles, allowing cars to talk to each other, would  avoid many crashes altogether by exchanging basic safety data, such as speed and position, ten times per second.



That is one way to create a market: mandate it.  The major mobile service providers possibly stand to  benefit, even if the actual communications will use the 5.9GHz band and Wi-Fi air interface (802.11p), in part because any such systems will benefit from wide area communications as well. 

But most of the revenue likely will be earned by application providers, in a complicated ecosystem.

The Department of Transportation's Intelligent Transportation System Architecture document attempt to bring some order to a fiendishly complex collection of technologies.
