It's known that installing FSD beta software disables radar for Autopilot and TACC, but I was surprised to find my radar immediately re-enabled when I opted out of FSD beta via the in-car button (restored 90mph limit and minimum following distance of 1).
I had assumed leaving the FSD beta program would require a software update before radar was re-enabled, but this is not the case. When I emailed [email protected] to be removed from the FSD beta program, they promptly pushed a software update to my car and said to also opt-out via the in-car button. I opted-out via the in-car button, but a failing 12V battery is preventing the software update from installing, so I am currently on 2021.36.8.5 (FSD BETA 10.4) with the ability to use radar-based Autopilot and TACC (to be clear - I can no longer turn on FSD beta).
Ideally, Tesla would allow switching between FSD beta and the radar-based Autopilot/TACC. I'm ok with testing FSD beta while I drive alone, but in my experience, the vision-only Autopilot and TACC are unusable with passengers in the car.
