After AP1 came out and continuing to a lesser extent through today, there have been numerous TMC posts with videos or reports describing what sounded like alarming and "unsafe" behavior. This includes AP1 allegedly driving cars into ditches, crossing double yellow lines, crossing lane lines, abruptly stopping next to or not recognizing parked cars, attempting to drive into trucks, not recognizing cars stopped in the road in front of them, causing drivers to become distracted and not pay attention to the road, and on and on and on. Given the constant clamor about how dangerous AP1 supposedly was, I think many people were very surprised to learn that when the data was in, the NHTSA found that activating AP1 actually reduced serious accidents by 40%.
The NHTSA report suggests that posts on TMC and other social media (including video in many cases) showing or describing apparently "unsafe" behavior were not only wrong, but got it completely backward. Cars with AP1 -- warts and all -- appear to be far safer than those without. And if the data holds up, AP1-enabled cars are not only safer, but with a massive improvement that is potentially unmatched in the history of automotive safety, except possibly by the seat belt. And AP1 continues to learn and improve and will undoubtedly only get safer.
So before jumping to the conclusion that AP2 is unsafe based on similar anecdotal reports/videos, I think it is worth taking a step back to consider why the anecdotal reports on how dangerous AP1 supposedly was were so misleading. The answer is that anecdotal reports are not data, and they are subject to all sorts of biases that skew the data, especially toward dramatic events that make a compelling story. There are numerous other kinds of biases at play as well.
The video you posted is a good example. Correct me if I am wrong, but this is not your video -- it is something you found on the internet. I also saw you post it on reddit, and perhaps you also posted it on other social media. Those posts will tend to heighten awareness of this example where AP2 did not perform well, and will tend to skew perceptions about AP2.
You chose not to post video or reports of AP2 doing well, of which there are many on TMC and elsewhere. I am not criticizing you for posting it, but just pointing out that this is an example of what happened with AP1, and explains why so many people who relied on anecdotal evidence incorrectly assessed AP1 safety. From this video and others I have seen, AP2 (like AP1) appears to do better on well marked roads that do not have sharp curves. Like AP1, it has learning to do with intersections because there are no lane lines. But that does not mean it is unsafe -- just as AP1's limitations do not make it unsafe.
Tesla has just recently released AP2 autosteer for use on surface roads limited to a relatively low speed (35 mph) with the driver instructed to keep hands on wheel and maintain responsibility for safe operation of the vehicle. There have been many reports of AP2 working well on well-marked and on some poorly marked surface streets. There have been some examples (like the one you posted), where this is clearly room for improvement, but the driver remains in control of the vehicle and can take over when necessary.
Bottom line: I don't think you have any basis for claiming AP2 is "unsafe" based on the video and anecdotal data. If history is any guide, Tesla's own assessment of the data is a more reliable guide than anecdotal reports/videos like the one you posted.
