I have two teslas and this is a non issue. The rare time it's happened it's a slow down, not a jerk. It just seems like FUD

Agreed. This used to be a big problem late last year for me (2021 M3 FSD). But I can't remember the last time it happened.

They should give drivers a simple way to notify Tesla exactly when phantom breaking happens. E.g. use the mic and when Tesla users say ‘Tesla phantom’ it would send the flagged data to a central repository to train against. Regardless of your feelings towards Tesla, we need someone to figure out safe self driving before the effort is halted and humanity has to wait a century before a new generation tries again (like…

the players in the early days of nuclear power weren't criminally negligent. self-driving isn't going anywhere while the states are still car-obsessed wastelands (which is to say never). it's climate cope. instead of changing the urban fabric, build some li-on powered self-driving cars and convince ourselves we're doing the work while we continue to hurtle to our doom.

2022 Model Y with FSD. I use Autopilot 50+ miles a day, and use it 98% of the way on trips from San Diego to SF. It infrequently phantom brakes, and more often brakes hard and late and sometimes people think I'm brake-checking them. It also is annoying slow to recover back to cruise speed from a slow down. Also if you're in the right lane when the two right lanes merge- it is totally unreliable, I've been sandwiched between an 18-wheeler and the gutter. But that said, once you learn the quirks it is extremely predictable and robust. I have used it on snowy mountain roads in Tahoe, a sandstorm at Salton Sea, and thousands of highway miles. If you have the minimum distance set to 2 or 3 car lengths, you should not be complaining about late and hard braking- that's the setting you chose. The phantom braking is annoying but infrequent, and you can quickly override it with an accelerator tap. My suggestion to Tesla would just be to have a debug button where you can report and elevate the past 10 seconds of driving.

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…

Happens to me all the time as well, I've got FSD (not the beta, the highway version, because apparently I take turns too quickly) and I have to be alert to bury the accelerator in case this happens on the highway. It's rare enough that I'm never quite prepared, but frequent enough that I know to be on my toes.

I've never seen it happen when I was following someone, I bet the software is biased to follow the vehicle in front even if one of these events happen. It happens to me when I'm headed up a hill and there is an overpass on the far side of the hill, or I'm passing a low overhead sign. I can understand why radar thinks it's about to slam into a wall, from the radar's low slung perspective I'm sure it just sees a barrier ahead. Considering Tesla's early penchant for driving right into the side of a truck, I do somewhat prefer the sudden braking.

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…

My vision-based Tesla rarely if ever experiences phantom braking unlike my previous radar-equipped Model 3 (it was pretty common in 2018 / 2019).

And you're still using this car? Why exactly?

Wait, do you think that Tesla are actually obtaining all driver video and manually adjusting the model based on reports like this? I've seen a lot of fanatics with no technology background claim this, but I'm...skeptical to say the least.

Because the rest of us are just crash test dummies. Nothing to see here, carry on.

Or autocorrect...

I doubt it. "Mollusk" is a term Johnny Depp used in a text to refer to him.[0] I could easily see it being used by detractors.

Besides the plows and grit, this CBC article claims the paint they choose has something to do with it: > Most of the paint is environmentally friendly but being water-based, it rarely lasts more than a year, especially on the province's busiest roads and highways. > "The paint used for highway striping eventually wears down as a result of the wear and tear from vehicle traffic as well as the effects of necessary wint…

You can be even more "environmentally friendly" by doing away with the markings, or even the paving...

The markings here seem to be some sort of dense plastic material and don't wear much.
