Q&A: Is Tesla's Autopilot feature dangerous?

The U.S. announced Thursday the first fatality in a wreck involving a car in self-driving mode. The government said it is investigating the design and performance of the system aboard the Tesla Model S sedan. A file picture dated 30 April 2015 shows a Tesla Motors Model S on a parking lot of the Tesla Motors Headquarters in Palo Alto, California, USA. Questions abound in the wake of the first death of a driver of a Tesla car with its self-driving features engaged. The National Highway Traffic Safety Administration, which has begun a preliminary evaluation into the fatal May 7 crash of a 2015 Model S electric car, said its probe centers on the car's'Autopilot' feature.
