A Tesla Model S with the Autopilot system activated was involved in a fatal crash, the first known fatality in a Tesla where Autopilot was active. The company revealed the crash in a blog post posted today and says it informed the National Highway Transportation Safety Administration (NHTSA) of the incident, which is now investigating. The accident occurred on a divided highway in central Florida when a tractor trailer drove across the highway perpendicular to the Model S. Neither the driver — who Tesla notes is ultimately responsible for the vehicle’s actions, even with Autopilot on — nor the car noticed the big rig or the trailer "against a brightly lit sky" and brakes were not applied. In a tweet, Tesla CEO Elon Musk said that the vehicle's radar didn't help in this case because it "tunes out what looks like an overhead road sign to avoid false braking events." http://www.theverge.com/2016/6/30/12072408/tesla-autopilot-car-crash-death-autonomous-model-s
