During a couple years of FSD usage there was a spot along my usual daily drive where the car came to a complete stop EVERYTIME I went West on that road. Two lane semi rural road, no traffic, sunny or night, NO STOP SIGN within 500 feet. Yet FSD stopped - no drama, just always came to a complete stop if I allowed it. Like it thought a stop sign should have been there. IIRC it started with some late flavor of v10 and eventually went away about a year into v11. Maybe that "activity" was replaced with the phantom, random wiper activity on every startup and while driving.

Key words "any longer"?? So it used to happen?

Yes. Phantom braking used to happen.

 

[JerryDuke]

Yeah, no phantom braking in a long time. But lately CURVATURE ASSIST has been a PIA! Kicks in on a straight road, no other cars near me.
I've been BUG REPORTing this every time it does it.
Two steps forward and SURPRISE, a new complaint.

But lately CURVATURE ASSIST has been a PIA!

What’s that ?

 

[JerryDuke]

Curvature Assist will slow down the car in a curve. It's inconsistent, invasive, sporadic, and a PIA.
It will suddenly flash CURVATURE ASSIST IS ACTIVE, the car slows down then sometimes will speed up to the speed the car was going when it activated. Some curves it does it, others it doesn't.

Google it, also Reddit has some comments.

I didn’t know something like this is linked to FSD. I thought this is a feature for the AP only (on cars who don’t have FSD), like those Tesla driven in UK or anywhere across Europe. Might be also for the North America Tesla, but I was using FSD in the last 11 months so I don’t have a clue.
The AP usually keeps the set speed, doesn’t care about the curve optimal speed and Tesla added the curvature assist to give the driver a somewhat experience closer to FSD driving, trying to slow down to match the optimal speed for the curve. But don’t expect to be perfect, IT IS NOT FSD. So why are you talking about Curvature Assist and FSD in the same sentence ? That’s why I was surprised and wanted you to explain what do you call "curvature assist".

 

[JerryDuke]

I'm using AP, not FSD, so I don't know if this is an issue with FSD.

I call it Curvature Assist because that's what Tesla calls it. If it doesn't apply to you, sorry.

No, this is a non-issue in FSD.

No need to be sorry, I thought you referred to it as a FSD feature, that’s all, and I wasn’t aware of such feature in FSD. I did watch a YouTube video presenting the feature in AP about a month or so ago. It was a video from a Tesla owner from UK.

My friend told me to be careful with Tesla because recently her friend’s Tesla stopped automatically on freeway and had a accident.
This seems very dangerous

I've been on a wide, 2+ lane road twice recently where the car in front pulled into a RH turn lane and my 2022 Mod 3 braked very hard. I was in cruise control going ~ 55 mph. Both times the cars were far enough behind to avoid crashes. The guy turning in front of me made a perfectly normal move and was well out of my lane.

Yes, HW3 equipped Tesla can have such behaviour.
