  • The final cut of TMC Podcast #27 is available now with topics time-stamped. We discussed: Consolidation in LiDAR manufacturers; Volvo EX90 shipping with LiDAR; FSD Beta Full Release in N.A.; FSD detecting autopilot cheats, Gwen Shotwell directly overseeing SpaceX Starship; and more. You can watch it now on YouTube. We should have it published to podcast networks shortly.

Multiple dangerous Autopilot regressions observed after accepted to FSD Beta

Interesting. I have never experienced anything like that at all. Looking at my log, I've driven over 6,000 miles on fsd beta and don't have a single strike (driving an MX) and I don't get phantom braking.
My Model S on AP or FSDb and on rural roads drives like a 15-yr old with restless leg syndrome, but my wife's Model X is smooth as silk and well behaved. The difference is like night and day. I'm very curious as to why that is.

I would recommend washing your car, then re-calibrate your cameras, then setup AP/NoA/FSD settings (calibration wipes them), and brake pedal reboot your car. See if it behaves better after that. Some people experience odd AP/FSD problems, but after a proper calibration find their situation improves. It may not solve your issue, but it doesn't hurt to try.

Thanks, but I've done all that more than once. I've got a good chance of things getting better on Aug 4. Tesla service is replacing the computer and several other items after it became possessed and systems started failing right & left. At the moment all I have is a fast manually-driven car.

Do both cars have FSD beta? Is the Model X running TeslaVision? Model S/X only went to TeslaVision earlier this year. One easy way to tell is max Autopilot speed on the older radar stack is 90mph and it's 85mph with vision-only stack.
 
OP, I have had the same problem as you. Several trips across New Mexico pre-FSD, and no problems. Last trip with FSD (EAP on the highway), and LOTS of severe phantom braking. I ended up "turning off" FSD when I got home. I haven't traveled much since then so I don't know if that helped or not. Very frustrating!
