No accidents yet and it's not safe by any stretch of the imagination! I have had some very close calls thanks to this "feature".No accidents or injuries attributed to it. Better to be safe than sorry?
Current UK M3 cars (including my M3P) have Tesla Vision with no radar and regular phantom braking.They're probably talking about the US Tesla Vision cars (no radar) which allegedly suffer from worse phantom breaking.
Likewise, TACC is something I simply don't use.I don't have Phantom Braking because I gave up using TACC in anything other than either empty roads or queues. But I am pleased that they are investigating this. Note however the report says M3 and MY from 2021 - is there a difference to earlier cars? My M3 is 2020 delivery and probably a 2019 build.
Are you sure? I was pretty sure mine (late December LR) wasn't Tesla Vision, based on the allowed follow distances in TACC when I checked. I can't remember the details, but supposedly the minimum follow distance you can set in TACC is different on radar cars and Tesla Vision cars...Current UK M3 cars (including my M3P) have Tesla Vision with no radar and regular phantom braking.
Lots of usage and no accidents SEEMS like it's safeR. Unsettling but safeR. Only by knowing the stats - with TACC and without, averages for other cars would you know. I've known a couple of mates (in other cars) that hit cars in front of them for silly reasons. One said "Yeah but I thought the car ahead of me had gone, there was a big gap"Good!

Tesla vision is US only. Apparently to remove the radar here they'd have to get it recertified, otherwise I'm sure they'd have done so.Current UK M3 cars (including my M3P) have Tesla Vision with no radar and regular phantom braking.

EDIT: Seems like the received wisdom was that if the minimum follow distance is 1, you have radar and if it's 2 or 3, you have Tesla Vision. (Of course, this may no longer be true with the latest firmware.) Will have to check mine again next time I use TACC.

I had thought that late '21 M3 cars were all Tesla Vision, but it seems that I was wrong and that this does only apply to the US. So thanks all for pointing this out. I did check my car and it is possible to reduce the following distance down to 1, which I understand is how to check whether there is a radar unit or not. I also understand that radar cars can have the cruise speed set as high as 90mph, whereas Tesla Vision is limited to 80mph. I haven't tried this one for obvious reasons, but the manual does give the maximum cruise speed as 150kmh, which is consistent with the car having a radar unit.UK cars are all still radar enabled
It can be one of many things
Fleet speed on off ramps or intersections, incorrect map data, the car thinking it’s in the wrong place or taking a different route (fairly common near off ramps) and others including poor road sign recognition.
On motorways and major trunk roads the car uses map based data and not vision for speed limits, so it’s at the mercy of the map data. Like wise, vision speed limits are at the mercy of the road signs and the system is not clever enough to not recognise a speed limit in a side road as not applying to the road that you are on.
If you said where it was occurring that could be investigated.
Also stamping on the brakes or lifting off? Lifting off can feel quite aggressive at times but not the same as a full on stomping of brakes.
I wish we could opt to have a 'dumb' cruise control. I just want my top speed capped. That's it! The phantom braking business is ridiculous.Likewise, TACC is something I simply don't use.
Disappointing, Mercedes "dumb" cruise control is more use.
