The TeslaAccording to preliminary results of the National Transportation Safety Board, Model 3 was involved in a deadly crash that occurred near Miami on Sept. 13, killing two people. Model 3 traveled as fast as 90 MPH before striking two trees and burst into flames.

The federal vehicle safety agency also found that the 20-year-old driver did not attempt to use the vehicle’s brakes during the five seconds of data that the NTSB was able to collect from electric car’s fire-damaged event data recorder.

The preliminary evaluation of data showed that acceleration was variable between 0 to 100 percent and that service brake was not engaged. Maximum vehicle speed recorded was 90 mph,” NTSB reported in its Wednesday report.

According to NTSB, the speed limit for the Coral Gables residential street where the accident occurred was 30 mph.

NTSB did not report on whether Tesla’s driver-assist system, which was marketed as both the Standard Autopilot and Premium Full Self Driving, were involved, or thought to have been involved, in the accident. The spokesperson of the NTSB refused to discuss any systems.

He stated in an email to CNBC that “the preliminary report is silent about this aspect.” “The investigation remains ongoing.”

NTSB (an independent federal safety agency for motor vehicles), investigates all causes of crashes. The NTSB also makes safety recommendations to automobile manufacturers, the Department of Transportation and other government agencies based upon their forensics.

Although the NTSB had issued safety guidelines to Tesla four years ago, Elon Musk, CEO of the company, has not yet adopted them. NTSB suggested that Tesla limit the use of automatic vehicle control systems in certain conditions. This could be, for instance, allowing only Autopilot and FSD to be used on highways or in mild weather. NTSB recommends that Tesla develop and implement better driver monitoring technology that can detect when someone is distracted from driving and not attentive on the roads. 

Jennifer Homendy (NTSB Chair) expressed concern at this situation in a letter to the companyOctober

NTSB launched a public appeal for videos or photos from anyone who witnessed the tragic crash of Sept. 13 in Coral Gables. Homendy praises Tesla for cooperating in this investigation and the one in Spring Texas.
