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.

The world is overflowing with autonomous cars. That's great because it breeds competition that will benefit everyone. The typical self-driving demo (while generally impressive), usually requires reporters to sit in the passenger seat while a safety engineer is behind the wheel. BMW on the other hand put me behind the wheel and let its prototype 5 Series tell me all about Las Vegas while barreling down the freeway. The BMW Personal Co-Pilot prototype 5 Series is a small taste of the automaker's long-term plans for the interior of its autonomous vehicles.
