I think Telsa just flipped the FSD "kill switch". I lost autosteer and cruise control on the way back from the store (after multiple phantom FCW's), after successfully navigating to the store on FSD. Now 2021.36.5.1 is downloading in my garage, which apparently removes FSD.
After getting a taste of FSD, honestly I think I'm appeased for the time being and can wait a little bit longer for a more fully baked version. This one apparently has a lot of regressions.
