“It actually regarded like I had loads of time to go throughout,” an anguished Florida truck driver stated in an interview transcript launched by the Nationwide Transportation Security Board this week. Sadly, he was improper.

Richard Wooden was driving a semi truck on the morning of Friday, March 1, 2019. He pulled onto Florida’s SR 7 from a driveway, aspiring to make a left flip. However as he crossed to the alternative lane, a Tesla Mannequin three belonging to Jeremy Banner crashed into the facet of the truck. Banner’s Tesla went underneath Wooden’s trailer, shearing off the roof and killing Banner.

The case attracted large consideration as a result of Banner had engaged Tesla’s Autopilot expertise. Not solely that, the circumstances of Banner’s loss of life have been nearly an identical to the primary Autopilot-related loss of life in america: the loss of life of Josh Brown in 2016. Brown was additionally killed when Autopilot did not cease for a semi truck crossing in entrance of him on a Florida freeway.

The truck driver’s interview transcript was certainly one of many paperwork the NTSB launched this week associated to 2 deadly crashes involving Tesla’s Autopilot. I hope to undergo paperwork associated to the opposite crash, Walter Huang’s 2018 loss of life, within the coming days.

“That dude did not make it”

The paperwork about Banner’s case present a number of new details about the circumstances of his loss of life. Based mostly on video footage, the NTSB estimates that the truck entered the roadway in entrance of Banner’s automotive about 4.5 seconds earlier than the crash. Banner was touring at nearly 70 miles per hour; the truck was touring about 10 miles per hour. Neither automobile slowed down or took different evasive actions throughout these 4.5 seconds.

In truth, Wooden says that originally he did not even notice {that a} deadly crash had occurred.

“I used to be going to take the left-hand lane and proceed on going north,” Wooden stated in an interview with authorities final March. “It is a very busy intersection… It is certainly one of them intersections the place you surprise why there is not a site visitors mild. However I’ve achieved it a dozen instances. I clearly thought I had loads of time.”

The crash occurred simply earlier than the solar got here up. Wooden says he noticed two pairs of headlights approaching, however believed they have been far sufficient away that he may get throughout the intersection simply.

“It was darkish and the automobiles regarded like they was again additional than what they was,” Wooden stated.

Then Wooden says he “felt a push towards my trailer.” He obtained out of his truck and “checked out my trailer and I seen particles caught within the facet of the trailer and it had a scuff mark down the facet of the trailer.” It was nonetheless darkish, he stated. “I assumed I had been concerned in a success and run.”

In actuality, the momentum of Banner’s Mannequin three carried the automobile far down the street—apparently up to now that Wooden did not see it when he obtained out of his truck. Wooden says it was only some minutes later, as he noticed the lights of emergency automobiles within the distance, that he realized the terrible reality.

“This man on this pickup truck come up and goes, ‘Are you the man that drives this tractor?’ I stated ‘yeah.’ And he goes, ‘That dude did not make it.’ I stated, ‘What are you speaking about?’ He goes, ‘That man—it sheared the entire roof off his automotive.'”

It was solely then, Wooden says, that the fact of the scenario totally hit him. “I went and obtained within the truck and I sit there till the cops obtained there as a result of I used to be simply shaking,” he informed authorities.

No apparent distractions

Driver distraction is ceaselessly a consider conditions like this, however the NTSB hasn’t recognized any apparent components impairing both driver. Wooden says that he did not use his mobile phone throughout that morning’s drive—a declare that appears to be backed up by mobile phone data. He informed investigators that he hasn’t had a drop of alcohol since 2014.

Nor did investigators discover proof Banner was impaired or distracted. “Cellphone data point out that the Tesla driver was not engaged in a telephone dialog and was not texting on the time of the crash,” an NTSB investigator writes. “The data additionally point out that the driving force didn’t use his telephone to textual content or name throughout the three mornings previous to the date of the crash.”

Information from Tesla signifies that Banner activated Autopilot’s traffic-aware cruise management function 12.three seconds earlier than the deadly crash. He then activated Tesla’s Autosteer function 9.9 seconds earlier than impression.

“Sensors within the Tesla didn’t detect the driving force’s palms on the steering wheel 7.7 seconds earlier than the crash,” the NTSB experiences.

It is a protected wager that Banner wasn’t wanting on the street forward of the automobile in the previous couple of seconds of his life. If he had, he absolutely would have observed a truck pulling out in entrance of his automobile. Even when he could not have totally stopped his automotive within the 4.5 seconds the automotive was pulling in entrance of him, Banner actually may have slowed the automobile down. But telemetry reveals that the automobile did not decelerate in any respect—suggesting that neither Banner nor the Autopilot software program realized {that a} crash was imminent.

Investigations into the 2016 Josh Brown crash revealed that (as my colleague Jonathan Gitlin wrote) “The machine studying algorithms that underpin AEB techniques have solely been educated to acknowledge the rear of different automobiles, not profiles or different features.” In the meantime, some driver-assistance techniques are designed to disregard stationary objects at excessive speeds, partially as a result of radar-based techniques have bother distinguishing objects within the street from objects which might be merely close to the street. There have been a number of circumstances the place Autopilot has steered Teslas into parked automobiles in broad daylight. It isn’t clear if these points have been a consider Banner’s loss of life, however we might study extra when the NTSB publishes its last report.

One factor driver-assistance techniques can do is to power drivers to maintain their eyes on the street. Cadillac’s Tremendous Cruise expertise does simply that, utilizing a driver-facing digicam to watch the place a driver is wanting. If Banner’s Mannequin three had had this function, he may need observed the truck crossing in entrance of his path and stopped in time to avoid wasting his life.
