"Self-Driving Tesla Was Involved in Fatal Crash, U.S. Says"

"DETROIT — The race by automakers and technology firms to develop self-driving cars has been fueled by the belief that computers can operate a vehicle more safely than human drivers.

But that view is now in question after the revelation on Thursday that the driver of a Tesla Model S electric sedan was killed in an accident when the car was in self-driving mode.

Federal regulators, who are in the early stages of setting guidelines for autonomous vehicles, have opened a formal investigation into the incident, which occurred on May 7 in Williston, Fla."
