Its just a matter of time before the injured and dead count starts increasing. Tesla needs to take their responsibility and disable AutoPilot before more people die because of its severe faults and flaws.

Currently the amount of injured and dead is falling for both Tesla cars and Tesla cars while on Autopilot.

I didn't realise Tesla Autopilot could raise the dead :)

You mean the rate? The total is very unlikely to ever decrease.

Can any other Traffic-Aware Cruise Control (TACC) stop in such a case? (Real question, I don't know). My current understanding is that Tesla's TACC is the best on the market. Correct?

I don’t think so. My understanding is that this is completely intended (and documented) behavior in Teslas and all other makes with this feature. Correct me if I’m wrong, but no adaptive cruise control systems perform full emergency breaking or emergency swerving when traveling at high speeds.

Here’s an an article from last year:

I drive a 2018 VW Golf Variant (Station Wagon) and the Adaptive Cruise Control from VW also has this problem. I regularly use it for city driving from traffic light to traffic light which means that I basically only have to steer a little, but if I'm driving towards a stationary car waiting in front of a red light, it will not detect the car until it starts to move.

What are we going to find out next, water is wet? Every radar cruise control system comes with a warning that it can't detect stopped traffic. This seems like a case of RTFM.

The issue is that tesla packaged up a radar designed for adaptive cruise control as part of their "autopilot." Maybe there is some disclaimer somewhere that says autopilot will happily run into stopped cars, but I don't know that most drivers of Teslas are aware of this.

I haven't found conclusive evidence, but the lack of news around other TACCs crashing into stationary objects is an indicator it might be a Autopilot specific issue.

Define best. It definitely has a lot of features few or no other systems have; on the other hand, it's a test program. It's officially Beta-Software, given to drivers to test and identify issues. So from a feature-set it's probably the best you can buy - but it turns you into a Test-Driver rather than a user of a product.

This has been true for a long time. Radar can't differentiate between a wall, a stopped car, or a dead skunk. Heck, it can get confused with a bridge's shadow on a bright day. Thus autopilot has to be configured to deal with these situations: stop or run into them. The vast majority of the situation you don't want the car to stop, as that will lead to a more dangerous situation and increase the chance of a collision.…

"Radar" absolutely can.

What can't differentiate between these things is the radar in Teslas that was intended for use in adaptive cruise control. There are any number of not insanely expensive radars that could do this job perfectly fine. Tesla just decided to go "full self driving" with this rather bad radar because "humans can do it with vision only!!!1!!!1!"

This is a deficiency in several automatic emergency braking systems [1]. Tesla extracts as much signal from front facing radar as they can, but edge cases abound. Marketplace or Planet Money had a piece a few weeks ago that mentioned the hardest problem was consumer education about these safety systems. People are inherently not interested in learning about the life safety systems in their cars. They expect it to “ju…

Without doubt it is Tesla’s fault, due to how they have named and marketed the feature. Even if they fixed the name, they have created a system that encourages people to disengage when it is not safe to do so. You can’t make a system inherently unsafe and absolve responsibility by adding a warning.

This not news. This has existed from the first iteration of Tesla Autopilots. That is why there where crashes with stationery vehicles for Tesla. This is shortcoming for using only cameras or any vehicle that has adaptive cruise control. The problem is that the front camera cannot distinguish from the road and a stationery vehicle. For that, they are the same and they ignore stationary obstacles. If they where taken…

This is something I don't understand. If you have more than 1 camera, you can run an edge detection algorithm on the images from each camera and use simple trig to build up a 3d model of what is in front of the car. This can easily distinguish between a shadow or road kill, vs a large object in the way. Is there a technical reason they don't do this (such as too much processing power required)?
