Sartre Vehicle Platooning

First demonstration of SARTRE vehicle platooning. 
Platooning may be the new way of travelling on motorways in as little as ten years time -- and the EU-financed SARTRE project has carried out the first successful demonstration of its technology at the Volvo Proving Ground close to Gothenburg, Sweden.

From Wikipedia: "Platoons decrease the distances between cars using electronic, and possibly mechanical, coupling. This capability would allow many cars to accelerate or brake simultaneously. Instead of waiting after a traffic light changes to green for drivers ahead to react, a synchronized platoon would move as one, allowing up to a fivefold increase in traffic throughput if spacing is diminished that much. This system also allows for a closer headway between vehicles by eliminating reacting distance needed for human reaction."
