Major Phantom Braking Issues

this silly thing is, Tesla has a fleet of several million cameras roaming the country every day. They have the perfect setup for a crowd sourcing model already in place.
Today on FSD I had a phantom breaking incident so abrupt it make my wife scream. No other cars were near so it wasn't dangerous but there was nothing I could see to cause the incident. It's one of the biggest flaws with Tesla automation and they don't seem to able to fix it.
For mapping and also for FSD training clips/telemetry.
"Tesla's unbeatable data advantage!" as often seen on the YouTube thumbnail banners. Effective clickbait, but also true.
yeah.. when you go from 83mph down to 40mph on a wide open interstate -within seconds and out of the blue - it definitely gets your attention....

Is there any more info from the car that stopped in a tunnel in CA and caused a pileup? People were claiming it was phantom braking or FSD but the available data didn’t fit with that.

We stopped using FSD a year ago. Don’t trust it and not taking any chances with getting rear ended.

I've actually found FSD to be better when it comes to phantom braking.

Better than TACC. I typically use FSD and don't use TACC much now, and since phantom braking has been a moving target with various updates there should probably be an asterisk by my statement.

FSD has been great since single stack, my only complaint is there is no way to completely disable all lange changes other than just not using the built in nav. The Minimal lange changes option helps, but i've still had it randomly decide to try and get to the other side of the freeway for no apparent reason.

pull the stalk twice for FSD, once for TACC, Duh!
I assume your question is because you're assuming TACC to be an integral part of FSD. IME, the two behave differently when it comes to phantom braking so there are cases where I'm using FSD and it won't brake while it does if I'm only on TACC.

Sort of. I have assumed when FSD is enabled with a ”stalk twice” maneuver that it enabled TACC by default, i.e., FSD is impossible without TACC. I’m wrong? Interesting that you have different behaviors with one over the other. For me, they behave identically wrt phantom braking.pull the stalk twice for FSD, once for TACC, Duh!

I think before they merged the software stacks FSD was completely separate from AP and TACC so there well could have been differences. If the code used for TACC is now the same as what they use for FSD then I'd expect the behavior to be identical. I use plain TACC pretty infrequently these days so I can't speak to the current behavior as much.

I think that's what I meant. I keep calling it FSD but it's autopilot I believe.
