A Spanish motorway played host to a convoy of self-driven cars on a 125-mile journey, in the first public test of such an endeavor. Each car was linked via a wireless connection, in groups – mimicking a manned vehicle as the group ‘lead’. Volvo, who developed this ‘road train’ is convinced that it will be widely available in the very near future – heralding a new age of ‘relaxed driving’; Volvo says drivers “can now work on their laptops, read a book or sit back and enjoy a relaxed lunch” while driving.
