Self-Drive Cars Test Travelled Over 125-Miles [bbc.co.uk]
A convoy of self-driven cars has completed a 200km (125-mile) journey on a Spanish motorway, in the first public test of such vehicles.

The so-called road train has been developed by Volvo. The firm is confident that they will be widely available in future.
