Anchorage,AK : Driver who died in Tesla crash on June, Monday 19th 2017

When Joshua Brown's Tesla slammed into the side of a tractor-trailer last year at more than 70 mph, the fatal accident became the world's first known car crash involving a partly autonomous vehicle.

Now, government investigators say that in the minutes leading up to the collision, Brown was audibly warned six times to keep his hands on the steering wheel. He was also warned visually, seven times, on his Tesla's dashboard.

In all, Brown had his hands off the wheel for 90 percent of his final drive, according to Tesla vehicle data reviewed by the National Transportation Safety Board. The NTSB on Monday released a roughly 500-page report detailing the facts of the case, but declined to provide a final analysis or judgment because the investigation is ongoing.

Included in the evidence are details about the highway where the crash occurred, both vehicles involved and, crucially, behavioral information from the Tesla that sheds light on Brown's activities immediately before the accident. The case is being closely watched, because the outcome of the investigation could affect consumer attitudes toward Tesla, automation and self-driving technology in particular.

Tesla spokeswoman Keely Sulprizio declined to comment on the NTSB report. In 2016, the company said Autopilot "does not allow the driver to abdicate responsibility," however.

Brown family lawyer Jack Landskroner said in an email the NTSB's findings should put to rest previous media reports that Brown was watching a movie at the time of the crash, which he called "unequivocally false."

He added that the family has not taken any legal action against Tesla and was still reviewing the NTSB report.

Brown's final drive in his Tesla lasted 41 minutes, according to the NTSB. Of those 41 minutes, 37 were spent with the autopilot enabled. Autopilot is Tesla's term for its high-end cruise control feature that can help a vehicle stay in its lane semi-autonomously. The company declined to comment on the report.

Tesla requires its drivers to keep their hands on the wheel even when Autopilot is engaged. But Brown appears to have ignored those warnings, even as he manually increased the autopilot's speed 2 minutes before he crashed into the truck, according to the NTSB report.

NTSB said Brown did not apply the brakes and his last action was to set the cruise control at 74 mph less than two minutes before the crash — above the 65 mph speed limit.

The agency said the truck should have been visible to Brown for at least seven seconds before impact. Brown "took no braking, steering or other actions to avoid the collision," the report said.

A Florida Highway Patrol spokesman said the truck driver was charged with a right of way traffic violation. He is due for a court hearing on Wednesday.

The NTSB report disclosed that the Tesla Model S uses a proprietary system to record a vehicle's speed and other data, which authorities cannot access with the commercial tools used to access information from event data recorders in most other cars.
