Tesla Autopilot predicts crash seconds before it happens

Tesla rolled out new software in September that leverages the forward looking radar to not only see directly in front of the car but around objects in front of the car. They interpret data bounced off of vehicles directly in front of the car to spot vehicles in front of the cars that are in front of the Tesla. This allows them to identify a decelerating vehicle before the driver in front of the Tesla can react, slowing the Tesla before the car directly in front of it even has it's brake lights on.

Yep. The video in this link doesn't work either, but they do have a gif. Basically, the Tesla goes "beepbeepbeep" about a second before the collision.

My Mercedes does that. It helped me avoid a collision recently too. I was driving home from work, tired and distracted momentarily by a pretty woman on the sidewalk when I hear three chimes, I look up and see the car in front of me is almost stopped so I slam on my brakes and stop about 3' short of him.

"Yes, Autopilot did avoid a crash here. But no, it didn't predict a crash. Not even close. What it did do was assist a driver that was relying too heavily on it. Remember, the key to driving is to keep your eyes up, not to hope radar will save you."

so it worked. neat, but hardly news.

And it's a feature that was on many other vehicles before Tesla added it.

BTW, it's now basically a mandated feature of passenger vehicles, so you will be paying for it.

In almost all cars, radar only see car that is in front of you - not car(s) that are further ahead.

Well, there were, and are, systems that use video cameras, not radar.

Also systems that use a combination of methods to sense what's going on up ahead.
That's what Tesla uses, a combination.

Radar can have some difficulty "seeing" through a metal object like a car or a big truck.
It's generally best to combine sensing methods.

Subaru, for example, has had a good system in place using cameras, since 2008.

Toyota's history of collision avoidance / mitigation technology is particularly interesting.

Tesla actualy bounces radar signal under vehicles to see what is in front of them - everyone else depends on line-of-sight detection. This allows to detect vehicles obscured by vehicle that is closer to you and blocks line of sight.

Infiniti has advertised such a system for several years and parent Nissan recently added to its brand of cars. I suspect everybody using radar has access to this data, it's just a matter of how much do you value that data? You could end up with Tesla's getting spooked by overhead signs:

"basically mandated", not mandated.

The gov't simply went with the agreement to get it done earlier.

https://www.nhtsa.gov/press-release...itment-20-automakers-make-automatic-emergency

The U.S. Department of Transportation’s National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety announced today a historic commitment by 20 automakers representing more than 99 percent of the U.S. auto market to make automatic emergency braking a standard feature on virtually all new cars no later than NHTSA’s 2022 reporting year, which begins Sept 1, 2022.

NHTSA estimates that the agreement will make AEB standard on new cars three years faster than could be achieved through the formal regulatory process.

The data visualization on the dash is usually pretty accurate (but very limited in range since the dash doesn't show very far ahead ever). It will mistake small trailers as a separate vehicle from the tow vehicle, but it works pretty well for the most part. I don't know if it is a new feature, or if in the past they just didn't bother drawing it.
