thecarchik writes "Scientists in Europe are working closely with industry and government as part of a new initiative called SARTRE (SAfe Road TRains for the Environment), which hopes to develop self-driving technology that will allow vehicles to drive autonomously in long road trains on the highway. The team behind SARTRE has now conducted its first real world test, using a sole Volvo S60 sedan that followed a lead truck around the automaker's test facility near Gothenburg, Sweden. In the video, the driver is free to take his eyes off the road and his hands off the wheel. In fact, he uses neither his hands nor feet during the test. Subsequent phases of the work will be carried out in 2011, and early 2012 will see the concept demonstrated on a five-vehicle road train with strategies handling interaction with other road users."
