U.S. auto-safety regulators are investigating the crash that killed 40-year-old Joshua Brown.
Those systems include automatic emergency braking, which is supposed to stop Tesla models from running into other vehicles detected by radar and a camera. This is based on the fact that If Tesla does not comply with NHTSA request of submitting information by August 26, then the company will have to part with $105 million. The information request is a routine step in an investigation, spokesman Bryan Thomas said.
On the first trading day that followed its June 30 announcement about the fatal accident and how its Autopilot was activated at the time, Tesla's shares climbed almost 2% to close at $216.50 on July 1. It also can steer the auto to keep it centered in its lane. In that crash, according to a report on Electrek, a clean technology transport news website, a Model X driver said Autopilot was engaged when the vehicle slammed into a guardrail.
Tesla faces up to $21,000 per day, with a maximum of $105 million, if it fails to meet NHTSA's deadlines for responding to the questions about the autopilot crash.
Meanwhile, another Tesla driver has told Montana police that Autopilot was engaged during an accident that occurred on Saturday. Tesla says the technology is still in public beta mode and drivers must confirm they know this before starting its use.
NHTSA's Thomas said he won't comment on specifics of the investigation. It is in the process of developing standards for self-driving cars.
Musk has defended the company's technology - the most advanced driver-assist system now available to consumers - as, on the balance, being safer than regular cars, noting the Florida accident was the first fatality in a Tesla linked to Autopilot. Tesla states clearly in its owner's manual that drivers should stay alert and keep their hands on the wheel to avoid accidents when the Autopilot feature is engaged. Allegedly the vehicle made a left turn in front of the Tesla at a junction. And NHTSA is looking into a July 6 crash in Pennsylvania in which a Model X flipped upside down while, its driver said, it was in self-driving mode. "He did not do so and shortly thereafter the vehicle collided with a post on the edge of the roadway", the statement said. Fortunately, neither the driver - who goes only by the last name Pang - nor his passenger were injured in the accident. "It's a winding road going through a canyon, with no shoulder", Shope told CNNMoney.
