Fatal Tesla crash reported to be using self-driving system

Authorities in Washington have determined that a Tesla that hit and killed a motorcyclist near Seattle in April was operating on the company's “Full Self Driving” system at the time of the crash.

Investigators from the Washington State Patrol made the discovery after downloading information from the event-data recorder on the 2022 Tesla Model S, agency spokesman Capt. Deion Glover said Tuesday.

“The investigation is still ongoing in this case,” Glover said in an email to The Associated Press. The Snohomish County Prosecutor will determine if any charges are filed in the case, he said.

Tesla CEO Elon Musk said last week that “Full Self Driving” should be able to run without human supervision by the end of this year. He has been promising a fleet of robotaxis for several years. During the company’s earnings conference call, he acknowledged that his predictions on the issue “have been overly optimistic in the past.”

A message was left Tuesday seeking comment from Texas-based Tesla.

After the crash in a suburban area about 15 miles (24 kilometers) northeast of Seattle, the driver told a trooper that he was using Tesla's Autopilot system and looked at his cellphone while the Tesla was moving.

“The next thing he knew there was a bang and the vehicle lurched forward as it accelerated and collided with the motorcycle in front of him,” the trooper wrote in a probable-cause document.

The 56-year-old driver was arrested for investigation of vehicular homicide “based on the admitted inattention to driving, while on Autopilot mode, and the distraction of the cell phone while moving forward, putting trust in the machine to drive for him,” the affidavit said.

The motorcyclist, Jeffrey Nissen, 28, of Stanwood, Washington, was under the car and pronounced dead at the scene, authorities reported.

Nissen's death is at least the second in the U.S. involving Tesla's “Full Self-Driving” system. In investigative documents, the U.S. National Highway Traffic Safety Administration said earlier it had found one fatality and 75 crashes while the system was being used. It wasn't clear whether the system was at fault in the fatality.

Tesla has two partially automated driving systems, “Full Self-Driving,” which can take on many driving tasks even on city streets, and Autopilot, which can keep a car in its lane and away from objects in front of it. Sometimes the names are confused by Tesla owners and the public.

Tesla says at present neither system can drive itself and that human drivers must be ready to take control at any time.

“Full Self-Driving” is being tested on public roads by selected Tesla owners. The company recently has been calling it FSD Supervised.

Musk said last week that he did not think approval by government regulators would be a limiting factor in deploying robotaxis. “If you’ve got billions of miles that show that in the future, unsupervised FSD is safer than humans, what regulator could really stand in the way of that?” he asked.

But Phil Koopman, a professor at Carnegie Mellon University who studies autonomous vehicle safety, said he doesn't see Tesla running robotaxis without human drivers on nearly all roads for another decade.

The safety record Musk cites is based on having a human driver supervise the automated system, he said. “Unless you have data showing that the driver never has to supervise the automation, then there's no basis for claiming they're going to be acceptably safe,” he said.

Musk has said Tesla will unveil a dedicated robotaxi vehicle at an event on Oct. 10. The event was delayed from Aug. 8 to make changes in the vehicle that Musk wanted.

Musk has been telling investors that Tesla is less of a car company and more of a robotics and artificial intelligence company. Many investors have put money into the company based on long-term prospects for robotics technology.

Musk has been touting self-driving vehicles as a growth catalyst for Tesla since “Full Self Driving” hardware went on sale late in 2015.

Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.
