  • (door slamming) (feet plodding)

  • (traffic buzzing)

  • - [Narrator] February 27th, 2021,

  • police body cam footage

  • shows a traffic stop

  • on a highway in Montgomery County, Texas.

  • - [Police officer] Hey, how's it going?

  • - [Narrator] As this 2019 Tesla Model X

  • driving in autopilot mode,

  • strikes their vehicles at 54 miles per hour,

  • injuring five officers,

  • and hospitalizing the subject of the original traffic stop.

  • - [Paramedic] Again, roll up, roll up.

  • One, one, two, three. (patient moaning)

  • - [Narrator] The crash is one of 16

  • between Tesla's and emergency vehicles

  • being investigated

  • by the National Highway Traffic Safety Administration

  • or NHTSA, to determine whether Tesla's Autopilot

  • has contributed to the accidents.

  • The journal obtained exclusive dashcam footage

  • and partial data logs from the Tesla in the Texas crash.

  • We annotated the footage for clarity.

  • These materials show the car's Autopilot System

  • failed to recognize the stopped emergency vehicles in time,

  • and though, its Driver Monitoring System

  • appears to have worked as designed,

  • it was not enough to sideline the impaired driver

  • and prevent the collision.

  • We also obtained eight Crash Reports

  • included in the NHTSA investigation.

  • In at least six,

  • the incidents occurred

  • when emergency vehicle lights were flashing.

  • NHTSA declined to comment on an ongoing investigation,

  • and Tesla did not respond to a request for comment.

  • (dramatic music)

  • The driver in the Texas crash begins his 45-minute trip

  • just before 12:30 AM.

  • "He is intoxicated," according to police reports.

  • The police investigation notes,

  • "Several instances when he swerves in his lane."

  • About four minutes into his drive,

  • the log show he sets the car on Autopilot

  • at a speed of 64 miles per hour.

  • Tesla's Autopilot is a system

  • that partially automates many driving tasks on highways,

  • including steering, braking, and lane changes.

  • Drivers using Autopilot are supposed to remain engaged

  • so they can take control of the car at any time.

  • Federal investigators have said, "Tesla's marketing,

  • including the name Autopilot, exaggerates its capabilities,

  • and encourages drivers to misuse the technology."

  • The Autopilot System for a 2019 Model X,

  • the model in the Texas crash,

  • judged whether the driver was alert

  • based on whether their hands were on the wheel.

  • If the system did not detect hands on the wheel,

  • the driver received an alert.

  • If the driver didn't respond,

  • Autopilot would disengage.

  • "The driver in the Texas crash

  • receives one of these alerts less than two minutes

  • after engaging Autopilot,"

  • according to the car's logs, and he complies.

  • He receives two more in the next minute, and complies.

  • In fact, he receives and complies with 150 of these alerts

  • over the course of this 45-minute drive.

  • By the design of Tesla's Driver Monitoring System,

  • the driver was paying enough attention

  • to operate the vehicle in Autopilot.

  • This year and model of Tesla

  • uses a combination of radar and camera technology

  • to recognize objects in all directions.

  • Autonomous vehicle experts say,

  • "The radar can easily recognize moving vehicles,

  • but that it has difficulty

  • distinguishing stationary obstacles,

  • leaving it mainly up to the cameras to detect them."

  • Around 15 minutes into the drive,

  • the logs indicate the technology is working.

  • It recognizes a vehicle about 120 yards ahead.

  • Then again, about 35 minutes into the drive,

  • the Tesla sees a vehicle as it merges 70 yards ahead

  • and tracks it as it drives off.

  • About 45 minutes in,

  • the Tesla approaches emergency vehicles

  • on the side of the road.

  • Autopilot is not designed to identify them as obstacles

  • because they're not in a lane,

  • but an attentive driver

  • would typically know to slow down or change lanes.

  • Around the same time,

  • the driver receives his 150th warning

  • to keep his hands on the wheel.

  • He complies, but it's not enough

  • to get him to respond to the stopped vehicles.

  • Seconds later, other police cars

  • are visibly blocking the lane,

  • but the logs show no sign that the Tesla sees them.

  • Experts in autonomous vehicle safety

  • who reviewed the crash footage

  • say, "There's a difference

  • between the way the car's camera sees an ordinary vehicle

  • and an emergency vehicle.

  • The police car's flashing lights created a hazy image

  • that the car's software likely did not recognize

  • as a stopped vehicle."

  • The logs indicate

  • that, "The car finally recognized something in its path,

  • just 2.5 seconds and 37 yards before the crash.

  • Autopilot attempts to slow the car,

  • and ultimately, disengages,

  • but at 54 miles per hour, it is too late.

  • The five officers injured in the crash

  • are suing Tesla,

  • claiming that "The Autopilot Feature

  • was responsible for the accident."

  • An attorney for the officers declined to comment.

  • Tesla denies the lawsuit's allegations,

  • and claims, "The fault lies with the driver."

  • The driver did not respond to attempts to contact him.

  • In 2021, after repeated recommendations

  • from federal investigators,

  • Tesla began using internal cameras

  • to monitor driver attentiveness,

  • but safety experts continue to find flaws in its design,

  • and drivers still find ways to fool the system.

  • The same year,

  • Tesla also issued a software update

  • that was designed to improve Autopilot's ability

  • to detect emergency vehicles.

  • Though one of the crashes NHTSA is investigating

  • occurred after these updates.

  • The government has now expanded its investigation

  • beyond crashes with emergency vehicles

  • and is investigating the overall effectiveness

  • of Tesla's Autopilot System.

  • And they could ask the company to recall the cars

  • if they find the technology flawed.
