It was announced in the TSLA stock thread. Original thread in Chinese: 特斯拉自动驾驶中国首撞！无视障碍物加速_网易科技 I believe this is a Chinese version of the Switzerland scenario for colliding a stopped vehicle. This is an Autopilot limitation that drivers should have learned from owner's manual as well as from Switzerland collision. Here's the diagram of what happened: The Model S (labeled blue) was locking on a moving leader car (labeled yellow). The leader car swerved right to avoid colliding to a stopped vehicle (labled black). The Model S (labeled blue) continued to drive straight to closely follow the leader car but also closely centering the lane without swerving and while it ignored the presence of the stopped vehicle. The Model S driver now realized an impending collision and grabbed the wheel to swerve right but it was too late and it swiped the stopped vehicle. Thankfully, the damage was minimal to both vehicles. The swiping was so minor that the dashcam didn't visually display a sudden shock: The moral of the story is: Please learn the limitations of the current Autopliot, be alert and avoid another replication of what already happened to others.
