Earlier this month, a Tesla Model X ping-ponged between the guard rails on the Pennsylvania Turnpike before flipping over and screeching to a stop. Oops, the car’s driver told the Pennsylvania State police when they arrived on the scene. He’d put the car on Autopilot.

The driver should have known better. The day before that crash, Tesla announced the first known fatality involving a self-driving vehicle — a man named Joshua Brown, who may have been watching a Harry Potter movie when his Tesla Model S confused the sunlight bouncing off a very large truck and drove straight into it.

Tesla reacted with a eulogy as tender as you might expect from a company that had just inadvertently killed its biggest fan. (Brown nicknamed his car “Tessie” and posted enthusiastic videos to YouTube of the vehicle routing itself around obstacles.) “The customer who died,” Tesla wrote on its company blog, “was a friend to Tesla and the broader EV community, a person who spent his life focused on innovation and the promise of technology.” Still, Tesla continued, the Autopilot feature is meant to be used with both hands on the wheel and eyes on the road.
