Tesla's automatic cruise effectiveness questioned

Original title: US Transportation Bureau slaps face Tesla: no autopilot can significantly reduce traffic accidents

According to the report on May 3, Beijing time, the U.S. traffic safety regulator on Wednesday refuted Tesla's claim that it had said that Tesla autopilot could significantly reduce traffic accidents. The regulator said it did not evaluate the performance of the assisted driving system in a 2017 report.

According to Tesla, autopilot is an advanced cruise control system that can handle some driving tasks and warn drivers to stay alert at all times.

The national highway traffic safety administration released the statement on Wednesday and is working with the National Transportation Safety Commission to investigate a fatal car accident in March. In this accident, the driver activated the autopilot function.

After the accident, Tesla mentioned an investigation report issued by the national highway traffic safety administration in 2017 in its response statement. In May 2016, a Tesla car crashed while using autopilot, causing the owner's death. After that, the national highway traffic safety administration investigated the accident and released the report. The report said that after the car was equipped with autopilot's' autosteer 'function, the traffic accident rate decreased by 40%, while reminding that the number was based on the data of Tesla's airbag activation.

However, the National Highway Traffic Safety Administration (NHTSA) said on Wednesday that its report 'does not assess whether autosteer is enabled or whether the technology is effective. '

It said that its 2017 report only made a 'rough comparison' of the use rate of car airbags before and after the installation of the autosteer function, so as to determine whether the traffic accident rate of Tesla models equipped with the autosteer function is higher. Therefore, 'further investigation is necessary'.

Tesla declined to comment.

Tesla said in March that the U.S. government said a year ago that its first generation autopilot could reduce traffic accidents by up to 40%. Tesla added: 'internal data confirm that recent upgrades to autopilot have steadily improved system reliability. '
