This happens to me just using the adaptive cruise control, no Autopilot or FSD enabled and it's super annoying. Can happen on a completely empty road driving in a straight line.

That's... appalling. My 2019 Leaf has absolutely zero problems maintaining distance with adaptive cruise control, using the ancient technology formerly known as radar. It can somehow even see stationary vehicles, something I thought wasn't feasible.

My 2019 Subaru Crosstrek has adaptive cruise control, and i've had it hit the brakes pretty hard when there's nothing in the way. Luckily it doesn't happen often.

Oh dear. Much worse than I expected by unexpected breaking; and FSD (Fools Self Driving) is involved in these problems, once again putting the lives of the driver and others at risk on the road.

> Tesla has drawn scrutiny from safety advocates and regulators for its willingness to allow its customers to test what is essentially an unfinished version of a software product that Musk has long promised will lead to fully autonomous vehicles on the road.

Now here's a similar recent scenario with 'blockchain'.

Suppose an unfinished 'beta' blockchain with multi-billions at stake going down or gets hacked and the price falls, is the excuse 'it's beta software', 'sorry you lost your savings'? Hence if many users of FSD beta are putting their lives at risk or getting themselves killed over faulty safety-critical software, is the excuse also going to be 'It's beta software'? 'Sorry you lost your life, you knew the risks!'

It really sounds like a way to push all blame on to the driver rather than the developer, despite little to no protections to the users and screams more tighter regulations to rid of that public 'beta' responsibility with software that has an incredible amount of risks.

How much better than a human driver does a self-driving system need to be before we as a society will accept fully autonomous vehicles? That seems like the key question which we are spending very little effort trying to understand. Until we have a national conversation about this, I suspect self-driving will be an intractable problem.

> Until we have a national conversation about this, I suspect self-driving will be an intractable problem. I hate to be a pessimist, but I'm not sure "national conversations" are all that useful in the U.S. Consider the "national conversation" leading up to Obamacare. NPR (at least) reported on the known pros/cons of various national healthcare systems around the world. AFAIK some of them were simply better than what…

For the ACA, whether it's better for you or worse for you depends on what income bracket you're in, whether you have preexisting conditions, and what kind of health care your job previously offered.

Whether it's better or worse for the country is a complicated question that I don't have an answer to, and no one does. Because it's a nuanced answer, if you're being serious about quantifying "better". Unfortunately most people, across both political factions in the US, would rather adhere to their ideologies than think critically about things in this era.

This is probably happening a lot more than the number of reports mentioned in the article indicates. It happens to me every other day in my Model 3. It's also not binary - sometimes it slows down more quickly than other times, or stops too suddenly when a car is stopped in front of you. Seems real easy to get rear-ended. I've only got autopilot, not FSD. It's very conservative. It always considers someone to be in fr…

I don't understand what you mean. You seem to be implying that if a driver rear-ends you he can use his dash-cam to show you were at fault? Most places I've driven it is the following car's responsibility to maintain a safe distance which includes being able to stop if the car you are following suddenly stops. Yes, brake checking is a thing and could complicate any civil suit, but mechanical (now software) failure wouldn't be that.

You continue using this feature despite these errors occurring daily? The way you describe it makes autopilot seem like an inexperienced teenage driver; I think whatever marginal safety benefit you get from it might be erased by the life-shortening stress such erratic car behavior must induce.

You cannot turn this behavior off persistently -- you need to open car settings and disable it every time you leave Park. My guess is that some jurisdictions mandate this behavior.

When this "feature" triggers you have a short window in which to do _something_ to tell the car that you are paying attention. Your options are either: accellerate or brake. If you do nothing the car may apply full brakes and bring you to a full stop, regardless what is behind you.

> Reports of “phantom braking” first surfaced last fall

This has been happening for much longer than that -- at least as early as Winter 2019, when I unintentionally brake checked a Prius after merging while going over 101 @ Rengstorf.

Most of the “driver aids” available today have the competency of a drunk or highly inexperienced driver. Just maintaining lane is a problem for all the systems I have had the opportunity to try. They are easily flummoxed by worn or moved lane lines (like you would see in a construction area). I view it as a definite upgrade over traditional cruise control, but it’s so far away from self driving it’s laughable to even think about.

To say nothing of the "inconvenience" to the driver who wasn't at fault but would have been assumed to be.

Can't speak for OP, but I'm supposed to be paying attention at all times while autopilot is enabled; as soon as I feel the vehicle may phantom brake, I apply more pressure to the accelerator to maintain speed.

I believe the NHTSA is going to require Tesla retrofit radar on all vehicles to mitigate their Tesla Vision functionality deficiency.

(submitted lengthy dash cam videos and accelerometer data to the NHTSA as a complaint)

Until we have a national conversation about this, I suspect self-driving will be an intractable problem.

It also isn't a problem that's binary, I think we could very easily end up in a situation where the AI is a better driver 99% of the time but will occasionally cause an easily preventable accident. Who will be liable once your self-driving car runs over a kid because it mistook them for road markings? I have the feeling that people are going to be more OK with explainable human accidents than unexplainable AI accidents.
