Did Tesla Autopilot Just Kill Someone?
A recent fatal accident could have major consequences for self-driving cars.
Tesla has confirmed that a recent fatal crash occurred in a Model S while Autopilot was activated, calling into question whether the technology is truly safe to be used in today’s roadways.
The National Highway Traffic Safety Administration (NHTSA) has opened a preliminary evaluation into the accident to determine whether Tesla Autopilot worked according to expectations. This is the first known fatality in just over 130-million miles where Autopilot was activated, and unfortunately it was just a matter of time before it happened.
According to the American electric automaker, the vehicle was traveling on a divided highway with Autopilot engaged when a tractor trailer drove across the highway perpendicular to the Model S. Neither Autopilot nor the driver noticed the white side of the tractor trailer against what Tesla calls a “brightly lit sky,” so the brake was not applied on the vehicle. Combined with the high ride height of the trailer and its positioning across the road, the Model S passed under the trailer, with the bottom of the trailer hitting the windshield.

It’s likely we will never know whether or not the accident would have occurred even if Autopilot wasn’t activated, but the unfortunate accident will shine a bright light on autonomous and semi-autonomous driving technologies. Swedish automaker Volvo has called out Tesla’s Autopilot saying that it is an “unsupervised wannabe,” while others have questioned whether it’s really safe to be “beta testing” a feature like Autopilot on today’s roads.
Tesla, of course, defended its Autopilot reiterating that the feature is disabled by default and that drivers acknowledge that they “need to maintain control and responsibility” for their vehicle at all times.
Read Tesla’s full statement below.
“We learned yesterday evening that NHTSA is opening a preliminary evaluation into the performance of Autopilot during a recent fatal crash that occurred in a Model S. This is the first known fatality in just over 130 million miles where Autopilot was activated. Among all vehicles in the US, there is a fatality every 94 million miles. Worldwide, there is a fatality approximately every 60 million miles. It is important to emphasize that the NHTSA action is simply a preliminary evaluation to determine whether the system worked according to expectations.
Following our standard practice, Tesla informed NHTSA about the incident immediately after it occurred. What we know is that the vehicle was on a divided highway with Autopilot engaged when a tractor trailer drove across the highway perpendicular to the Model S. Neither Autopilot nor the driver noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied. The high ride height of the trailer combined with its positioning across the road and the extremely rare circumstances of the impact caused the Model S to pass under the trailer, with the bottom of the trailer impacting the windshield of the Model S. Had the Model S impacted the front or rear of the trailer, even at high speed, its advanced crash safety system would likely have prevented serious injury as it has in numerous other similar incidents.
It is important to note that Tesla disables Autopilot by default and requires explicit acknowledgement that the system is new technology and still in a public beta phase before it can be enabled. When drivers activate Autopilot, the acknowledgment box explains, among other things, that Autopilot ‘is an assist feature that requires you to keep your hands on the steering wheel at all times,’ and that ‘you need to maintain control and responsibility for your vehicle’ while using it. Additionally, every time that Autopilot is engaged, the car reminds the driver to “Always keep your hands on the wheel. Be prepared to take over at any time.’ The system also makes frequent checks to ensure that the driver’s hands remain on the wheel and provides visual and audible alerts if hands-on is not detected. It then gradually slows down the car until hands-on is detected again.
We do this to ensure that every time the feature is used, it is used as safely as possible. As more real-world miles accumulate and the software logic accounts for increasingly rare events, the probability of injury will keep decreasing. Autopilot is getting better all the time, but it is not perfect and still requires the driver to remain alert. Nonetheless, when used in conjunction with driver oversight, the data is unequivocal that Autopilot reduces driver workload and results in a statistically significant improvement in safety when compared to purely manual driving.
The customer who died in this crash had a loving family and we are beyond saddened by their loss. He was a friend to Tesla and the broader EV community, a person who spent his life focused on innovation and the promise of technology and who believed strongly in Tesla’s mission. We would like to extend our deepest sympathies to his family and friends.”
