Several European engineering firms are collaborating on new technology that would allow cars to drive you, rather than the other way round. The so-called road train system is made up of a lead truck which other motorway vehicles would link up to and follow, using a mix of radar, camera and wi-fi technology.

The "ultimate cruise control” would allow a driver to take his hands off the wheel, feet off the pedals and relax while the computer system takes control. Scientists say hands-free driving will cut fuel consumption, reduce congestion and makes road safer. Btw, one of the most famous automobile companies using this gadget is Volvo. They already set the ultimate cruise control on their cars.
