I'm wondering when the Tesla beeps if it reacts to the behavior of the red car or instead to the cars braking in front of the red car?

#42Lots of mainstream cars (Nissan, Ford erc) can already do this.
Did you watch the video with sound on? The car alerts before the car in front brakes.

#43> software update enabled Teslas to “see” through vehicles traveling immediately in front of them. In this case, however, the Autopilot seems less like X-ray vision and more like straight-up clairvoyance I don't believe the car is clairvoyant, but my guess is radar bouncing off the asphalt under the cars. And maybe a glimpse of the brakelights?
Yes, Tesla is using signal processing to detect radar reflections of the car in front of the car in front of you. They showed this when they introduced the firmware with this feature.

It reacts to the car breaking in front of the red car - the trick is to use radar reflections of both the red car and the one in front of it, which propagate below the red car. This feature was advertised with a recent firmware update.

#45I thought this an interesting video when Elon retweeted it. Basically the car is responding faster than the people do and keeping things from escalating. That said, having been on 101 when the cars in front start dancing like that I have to say my biggest worry isn't stopping in time its having someone behind me not stop.
Because Tesla brakes faster than a human in this situation, it doesn't have to brake as much, it can slow down in a timely manner.
Also sudden hard brakes can cause injuries as well when the seat belt it tighten suddenly, but the software based braking will brake more accurately than a human, as you said in a timely manner.

I have seen plenty of 3 car accidents and the last car involved in the accident is purely because it could not brake on time and the first 2 cars involved in the accident are due to human stupidity.
I live in Dubai and it is a mix of many cultures and people drive like crazy here, I have seen a single accident involving 6 cars because most of the rash drivers will drive tail-gating
At least Dubai really needs lot of Tesla cars to avoid such accidents which are very common here

#47One part of my brain is saying: Sweet piece of technology!!! Another is saying: This seems like a very convenient piece of good PR for Tesla (and self driving car technology)... Yet another is saying: I hope the folks in the car are alright
Relying on error-prone, distracted, slow humans to guide massive killing machines is playing Russian roulette. AI driving will no doubt be eventually better than the best human driver within a decade, in nearly all instances.

That's why I usually break fast initially and check the rearview; extend the braking distance to allow extra room for the person behind if they are too close.

Great habit, but after seeing over 10,000 charts for chiropractic cases (was working on IT software to categorized it) I learnt another trick that many doctors tell their patients (unfortunately after the fact):
Once in a emergency breaking situation, before you look into the mirror, secure your neck/back of your head as hard as you can into the headrest cushion. This trick will "unite" your head with the seat and in rear-end, it will push you and the car both at the same time, instead of - from what I seen in 80% of Chiro cases - your seat head cushion hitting your head in a moment when its pulled hard to the back due to G-forces related to being in a rear-end.
I have to say seeing some photos I quickly got into a habit of first doing that, next checking mirror - if I assume someone might not make it and I still have room upfront, I go forward as fast and as close as I securely can.

#50Here is a video by Bjørn Nyland demonstrating the ability of the Tesla radar to detect the motion of the car in front of the car you are following: https://www.youtube.com/watch?v=cG3Jp5GyPoc
It shows, how the radar detects, that the lead car breaks first - watch how it gets highlighted in the dashboard. This ability helped the Tesla to handle this accident event.
