Currently, driverless vehicles are only permitted on private roads, but the UK government is to outline plans that will introduce test cars onto the UK's public roads from January 2015.

The Department of Transport will begin reviewing public road laws to accommodate self-driving cars, with Business Secretary Vince Cable announcing a £10 million prize fund to be awarded to a town or city to host the trials.

You're probably already aware of Google's involvement in driverless cars, but a number of other major manufacturers, including Ford, Toyota, BMW, Hyundai and Audi are currently also working on driverless technology.

Volvo's another one beavering away at autonomous vehicles. Nick Connor, Managing Director of Volvo Cars, told us in a statement: "We're currently working with authorities in Sweden on a similar trial in Gothenburg for our DriveMe programme of self-driving cars. Support of national and local government is crucial if we are to demonstrate the real life-changing potential of this technology and encourage adoption from the public.

"Driverless cars aren't pie in the sky or innovation for its own sake. They can make our roads safer, our air cleaner and our cities less congested."
