Elon Musk shakes up Tesla as another Model S faces crash queries

The National Transportation Safety Board is investigating a crash and fire involving a Telsa Model S car. Two teens died in Fort Lauderdale, Florida crash on Tuesday. The probe is not expected to involve Tesla's semi-autonomous Autopilot system. A Tesla sedan with a semi-autonomous Autopilot feature rear-ended a fire department truck at 60 mph (97 kph) apparently without braking before impact on May 11, 2018, but police say it's unknown if the Autopilot feature was engaged. SAN FRANCISCO -- Tesla's week started with a bang Monday as CEO Elon Musk announced a management "flattening" designed to meet make-or-break manufacturing goals while Utah police investigated why a Model S hit a stopped fire truck at 60 mph.
