A six-month investigation failed to uncover any flaws with the autopilot's emergency breaking technology and other advanced features linked to a deadly accident past year, according to a National Highway Traffic Safety Administration (NHTSA) report released Thursday.
"Our investigation was thorough, evaluating every aspect of the Tesla Autopilot system including the automatic emergency braking system", Bryan Thomas, NHTSA's communications director, said in a conference call on Thursday.
In addition to examining data, NHTSA took other measures, including surveying the crash site, and conducting road tests using a 2015 Tesla Model S 85D, which is similar to the auto that crashed, and a 2015 Mercedes C300 4Matic, as a "peer vehicle".
Joshua Brown, 40, was killed in May 2016 while using the feature in a Tesla Model S during a collision with a trailer of an 18-wheeler that crossed the road in front of the Model S. "NHTSA's crash reconstruction indicates that the tractor trailer should have been visible to the Tesla driver for at least seven seconds prior to impact".
US INVESTIGATORS say they have not found any fault with the automatic braking system on the Tesla Model S involved in a fatal vehicle crash previous year.
After being given crash data by Tesla, which compared cars with Autopilot and those without, the investigators determined installing Autopilot prevents crashes by 40%.
The agency said Brown "should have been able to take some action before the crash, like braking, steering or attempting to avoid the vehicle".
Auction ends Tuesday for Trump's home in Queens
The property was originally put up for sale for $1.6 million in 2016, though that price was later reduced to $1.2 million. It'll go up for auction today via Paramount Realty , though a starting bid for the home has not been released.
The crash sparked a series of debates over the reliance drivers should put into autonomous driving technology and even the kind of language Tesla should use when describing its technology. He explained that there are driving scenarios that the Autopilot's emergency braking systems are not created to address.
"The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists".
In the months since the probe was announced, Tesla rolled out a radar-based upgrade that provides a "dramatic improvement in the safety" of Tesla's Model S and X electric vehicles, according to CEO Elon Musk. His case was the first fatality in a Tesla vehicle and has since raised questions about the safety of autonomous vehicles.
In a brief statement, Tesla said it appreciated the department's quick response to the investigation. The company has said that before Autopilot can be used, drivers must acknowledge that it's an "assist feature" that requires both hands on the wheel at all times and that drivers must be ready to take control.
A precursor to Tesla's fully autonomous technology, now in development, Autopilot would have faced a recall if the report had found it defective.
The NHTSA took mileage and airbag deployment data from Tesla and conducted an analysis to see how Autosteer affected the number of accidents that Tesla vehicles were involved in.
Tesla has avoided a recall of its cars after the US National Highway Traffic Safety Administration (NHTSA) closed an investigation into a crash in which a driver died.
