While the video title incorrectly states that Autopilot saves the day (Tesla's without autopilot can still have auto braking, provided the sensors are in place), it's still rather remarkable to see this Tesla brake on its own to prevent what could have been a catastrophic accident.
Here's the video description:
"Add your own honking and swearing.
Was travelling a little under 45 mph. There was some rain, but roads were pretty dry. I was watching stopped traffic to my right.
I did not touch the brake. Car did all the work. Sadly no audio, because I had an Uber passenger and Washington has strict privacy laws about recording conversations."
So, while the driver was distracted by stopped cars, auto brake brought the Model S to a halt just before colliding with the car that made a ridiculous turn in front of traffic.
