On March 10, Tesla, an electric vehicle manufacturer, insisted in a letter to two senators that the company's driver assistance driving system autopilot and its upgraded version of "fully automatic driving" (FSD) were safe enough. However, senators do not seem to believe this and say Tesla is evading and distorting the facts < p > Rohan Patel, Tesla's senior director of public policy, wrote to US senators Richard Blumenthal and ED Markey on March 4: "Tesla's autopilot and FSD features enhance our users' driving ability and are even safer than ordinary drivers in the United States." < p > in the public comments on the fspilot and other articles, musk is more cautious. For example, in a recent earnings conference call, musk claimed that by the end of 2022, FSD will be safer than human driving. Patel did not mention the date, but he insisted that Tesla's advanced driving assistance is indeed safer than human driving < p > Patel, for example, said: "in the fourth quarter of 2021, Tesla cars that activate autopilot system will have a traffic accident every 6.94 million kilometers, while the latest data from the National Highway Traffic Safety Administration (NHTSA) shows that vehicles in the United States will have an accident when they travel an average of 780000 kilometers." < p > Tesla occasionally publishes safety reports corresponding to these data in an effort to promote autopilot as a safer system than human driving. But experts point out that these data are largely meaningless because autopilot is mainly used for highway driving. Tesla has an unfair advantage over national statistics that include a variety of driving environments, including residential and urban driving < p > Patel then described Tesla's driver monitoring system, which uses torque sensors on the steering wheel and cockpit cameras to monitor driver behavior. However, he did not mention that regulators and safety experts have been asking Tesla to add better driver monitoring systems to its cars for years. Musk even admitted that the traffic accident involving autopilot was due to complacency, and he rejected his engineers' request for more monitoring on the company's cars, saying the technology was "ineffective" < p > however, cars currently sold by companies such as general motors and Ford are equipped with camera based eye tracking systems to ensure that drivers pay attention when using hands-free driving < p > If Patel wrote to ease Blumenthal and Markey's concerns about Tesla's security commitment, it didn't seem to work. "Tesla is more evading and distorting the facts. Despite its disturbing safety record and fatal crash, the company seems to want business as usual. Tesla should have received the message: abide by the law and put safety first," the senators said in a joint statement < p > given that Tesla has always been regarded as one of the safest cars on the market, senators have not provided data to prove that the company has a "disturbing safety record and is responsible for fatal crashes". In many accidents involving Tesla cars, some were attributed to autopilot, but it turned out to be the driver's human error. However, as of the time of this article, Tesla has not responded to Blumenthal and Markey's comments < p > < / P > < p > Tesla is currently launching the FSD beta project, which allows vehicles to drive automatically on urban streets. Now, the project has covered about 60000 users in the United States. (small) < / P > < p >
