BBC NEWS | Technology | 'Road trains' get ready to roll: "oad trains that link vehicles together using wireless sensors could soon be on European roads.

An EU-financed research project is looking at inexpensive ways of getting vehicles to travel in a 'platoon' on Europe's motorways.

Each road train could include up to eight separate vehicles - cars, buses and trucks will be mixed in each one.

The EU hopes to cut fuel consumption, journey times and congestion by linking vehicles together.

Early work on the idea suggests that fuel consumption could be cut by 20% among those cars and trucks travelling behind the lead vehicle."
