content: This is just not correct. Look at the video. The car first beeps at the start of 5 seconds when there was plenty of space between the driver and the car in front. The crash doesn't happen for nearly a full 2 seconds. What started the beeps was what a human can not see: the car in front of the car in the front of the Tesla suddenly braked, but the human in the car in front of the Tesla did not respond quickly enough resulting in collision-bound trajectory. The Tesla started slowing down before the crash even happened, in anticipation of it. This feature, of being able to adjust to actions from vehicles ahead of the one immediately in front of you is new and was added only in September.
