The National Highway Traffic Safety Administration (NHTSA) is now taking up two fatal Tesla crashes potentially involving Autopilot, both of which coincidentally occurred on the same day, December 29. The first, in Gardena, California, involved a Model S running through a stoplight and crashing into the side of a Honda Civic, killing both occupants in that car. This latest investigation, first brought to light by Reuters earlier this week, involves a married couple in a Model 3 who collided into the rear of a fire truck on Interstate 70 in Cloverdale, Indiana, just west of Indianapolis. According to the Indianapolis Star, Derrick Monet, 25, hit the truck—which had its lights flashing while parked in the left lane—at a high rate of speed. His wife, Jenna Monet, 23, was in the front passenger seat. Both were taken to a local hospital where she was pronounced dead. The State Police report says the driver "failed to observe the emergency vehicle positioned in the passing lane of I-70, running into the back of the parked fire truck."
