Back in November 2009 I mentioned the concept of Road Trains being developed in Europe. At the time it was just a concept and everything was mostly tested using simulators. Well not any more. Europe’s SARTRE (SAfe Road TRains for the Environment) project carried out its first successful real-life demonstration of its self-driving technology at Volvo’s proving grounds near Gothenburg, Sweden, and recorded it for us all to see...

Pretty impressive. All you need now is for your car to talk with a KITT voice and you'll be set for your long relaxing economical journey across mainland Europe with the Knight Rider theme tune blaring out your speakers.

I wonder if we'll get these in the UK before we get high-speed rail :-)
