Autopilot does emergency braking for nonexistent obstacles. I'm sure it's contributing to rear end collision risk. I stopped using it for this reason.
Every autonomous braking system has that problem, including the one in my 2020 Macan. They are dangerously-flaky hacks. As of 2025 they are mandated by law.
Given Tesla's now well-documented history of lying about their cars' safety,[0-6] it's kind of alarming to see, what's basically an ad directly from a brand, being posted to the front page of HN [0] https://www.washingtonpost.com/technology/2019/08/07/federal...

Yeah, I can't even imagine what it would be like to implement a system like that without radar. Tesla's approach would make a good Most Interesting Man In the World meme. "I don't always tackle the hardest engineering problems in human history, such as self-driving cars. But when I do, I tie one hand behind my back, close one eye, and consume some alcohol or drugs first." One episode per 3000 miles is too many, and t…
Are you referring to the "gentle slow down" behavior that Autopilot often does or the "slam on the brakes as hard as you can" behavior of Automatic Emergency Braking? I definitely see the former more than once per 3000 miles but it doesn't bother me. I've never seen the latter.
If someone has built an AEB system with the degree of immunity from false triggers that's needed to make it a net positive for road safety, I haven't seen any evidence yet. Similar complaints across many different car models are widespread.
Comparing Tesla to the US incident average is a neat way of ignoring that high-end electric vehicles are not driven by the US average driver, in average situations. The driver (or should we call them executives, in self-driving cars?) is likely to have much more to do with the statistics, that the car.
More important is the fact they are driven by older people (median age 48 years old), that is more important.

It's absolutely amazing that we have to go through this every time someone gets video of a Tesla event. There are millions of these cars on the road now, surely the fact that this happens only monthly sits as evidence against your position, no?
Edit: FWIW: my money is on this story being quietly retracted at some point anyway. FSD doesn't behave like that. It just doesn't. Almost certainly the driver got confused, panicked, or otherwise overrode the automation and then blamed it when talking to police. The police report is almost silent on the subject: https://www.documentcloud.org/documents/23569059-9335-2022-0...
This entire kerfuffle is based on this one sentence: "P-1 stated V-1 was in Full Self Driving mode at the time of the crash, I am unable to verify if V-1’s Full 24 Self-Driving Capability was active at the time of the crash."
> For example, more than 35% of all Autopilot crashes occur when the Tesla vehicle is rear-ended by another vehicle. Well, if you want to know why some people are rear ending a Tesla, it's because it's far more unpredictable than a human driver. https://theintercept.com/2023/01/10/tesla-crash-footage-auto... Also it seems to contradict itself on data collection. First; > In practice, this correlates to nearly any cra…
Does the Tesla always activate its brake lights when slowing down? (I have an EV6, and I don't even know if brakes lights come on when I'm using regen as opposed to the brake pedal) When I'm driving and traffic is stopped ahead, I used to always brake not because I had to, but as an indication to the car behind me.
In comparison, my 2015 Leaf doesn't illuminate the brake lights during regen but it's regen is significantly less than my Model 3.

I own another VAG car with automatic emergency braking. If it is actually applying the brakes for you more than in cases where you are clearly about to rear-end someone, you should consider not tailgating as much. The sensor even gives you a warning if you are following too close at highway speeds. The radar system they use in modern VW and Audi cars is extremely conservative, claiming to not engage the brakes at all…
I love my 2021 RS 5, but I have to disagree with this. Even in Traffic Jam adaptive mode, many times it will accelerate towards a vehicle _that it detects_, and only brake very late, and hard. On several occasions I've intervened because I wasn't sure if it would. When I've been alone in the car, I've waited later (and seen it brake hard, of its own accord), when I've held off on the brake since I have no passengers to give whiplash.
It will also absolutely emergency brake above 35mph.
I do believe that Teslas are quite safe despite the high-profile failures, but I'm very unconvinced by a stat that compares accidents per mile using autopilot to accidents per mile not using autopilot. Those are not comparable miles - people don't uniformly use autopilot across all driving conditions. Imagine you had a subsystem that did absolutely nothing, but people turned it on when driving on empty highways. It's…
This needs to be emphasized so much more. Short of "not driving", human drivers don't have the option of "well, this is less than optimal, I can't do well, so I won't try". FSD absolutely does. Disengages, or is not even engaged in the first place. I wonder Tesla's FSD safety / disengagement stats for December to February in Pittsburgh, for example.

Almost as upsetting as it is to see a Gish gallop link list rise to the top of that topic. Needless to say not one of those corroborates "history of lying about their cars' safety", and you surely know that. But you'll challenge us all to figure it out on our own anyway? It's absolutely amazing that we have to go through this every time someone gets video of a Tesla event. There are millions of these cars on the road…
