According to Walter Isaacson's new biography Elon & middot; Musk (Elon Musk), Tesla CEO Elon & middot; Musk (Elon Musk) nearly died many times during a test drive due to Autopilot, making him furious with engineers, according to the new biography of Walter Isaacson.

In the chapter on self-driving assistive technology in the biography, the author reveals an event that Musk experienced personally: there was a bend on Interstate 405.As the lane of the road had faded, the Autopilot could not recognize it, causing the car to turn and & ldquo; almost hit the oncoming vehicle & rdquo;.

Whenever this happens Musk & ldquo; & rdquo; rushes into Tesla's office and is furious with his engineers who repeatedly ask them to improve the program: & ldquo; do something to program this thing correctly & rdquo;.

In addition, Musk insists that Tesla's car only needs to use optical sensors, just as humans drive mainly with their eyes. He refuses to use other technologies, such as lidar (LiDAR), as too expensive and unnecessary. The biography says his engineers thought lidar was the best way to improve security, but they couldn't persuade Musk to change his mind.

At the same time, Musk also forced Tesla to cancel the millimeter wave radar. Musk has revealed that radar perception does have an advantage in special weather.On the whole, however, most driving scenarios are useless, and there will be trouble with data processing due to increased redundancy.

Tesla promised that the vision system could meet the level of autopilot, but judging from so many complaints from ldquo; Ghost car & rdquo;, many car owners were still not convinced by Tesla's promise.
