BMW shows off 'drifting' self-drive cars

BMW has shown off self-driving cars that can "drift" around bends and slalom between cones.

The modified 2-Series Coupe and 6-Series Gran Coupe are able to hurtle round a racetrack and control a power slide without any driver intervention.

Using 360-degree radar, ultrasonic sensors and cameras, the cars sense and adapt to their surroundings.

BMW demonstrated its latest autonomous driving technology at the Consumer Electronics Show (CES) in Las Vegas.

It is just one of several car manufacturers experimenting with the technology - Japan's Toyota has also been demonstrating its autonomous car at CES.

And Bosch, better known for its white goods and power tools, showed off its smartphone-controlled self-parking technology at the show.
