A Utah driver who slammed her Tesla into a stopped firetruck at a red light earlier this year while using the vehicle’s semi-autonomous function has sued the company, saying salespeople told her the car would stop on its own in Autopilot mode if something was in its path. Heather Lommatzsch claimed in the lawsuit filed Tuesday that Tesla salespeople told her in 2016 when she purchased the Model S that she could just touch the steering wheel occasionally while using the Autopilot mode. Lommatzsch, 29, said she tried to brake when she saw the stopped cars, but that the car’s brakes did not work.
