What happens when Tesla’s AutoPilot goes wrong: owners post swerving videos

Early adopters share hair-raising videos of their Model S cars veering into traffic as new feature proves very beta

Tesla's latest software update gave its Model S electric car the ability to drive itself with a new AutoPilot mode, but as a collection of owners have found out, two hands on the wheel are most definitely needed at all times.

The new feature, released in beta, uses radar and camera sensors to detect the distance to cars in front to judge speed and brake, while monitoring the white lane lines to guide it round corners. Several other cars from Volvo, Mercedes, Audi and others do similar, but have yet to be able to change lanes like Tesla.
