Why and how to joyfully move our butts around town, without mucking the place up.

Connected vehicles and vehicle-to-vehicle communications

What if cars and trucks could communicate data with each other on the road, and automatically avoid crashes? Research is underway in several locales for just that purpose.

Road Trains are one possible use, where a group of cars form a "platoon" of vehicles driving as if they were a unit. Computerized gizmos on-board keep the vehicles in the road train informed of what the other vehicles are doing, and automatically keep them moving at the same speed and spacing between vehicles. Computers can do this more efficiently than humans could, and with potentially greater safety.
