Has Teslascope referred to single stack / FSD Beta 11 as the same as wide release / toggle? I'm pretty sure they're well aware of the difference, but the confusion for some people is probably because both milestones have been targeting end-of-year release. It might end up being the same single release as a Holiday Update Part 2, but time is indeed running out for either one to happen this year let alone both.
Here's a quick summary of the two milestones. Single stack / FSD Beta 11 is referring to having FSD Beta's city streets driving behavior replace the legacy highway driving that has powered Navigate on Autopilot, and Autopilot team has been working towards this
since July 2021 incrementally adding capabilities as part of FSD Beta 10.x. Wide release / toggle is referring to the likely end of the "safety score" testing group that started with FSD Beta 10.2 in October 2021 where people needed to push a request button and wait for Tesla to push separate software to the vehicle, and instead the regular production vehicle software would go to "everybody" like before FSD Beta and include a toggle in the Autopilot settings screen to directly enable "Full Self-Driving (Beta)" without waiting for separate software.
To be clear, since November, Tesla has deployed single stack wider than internal alpha testing to a group of stricter NDA employees while the intent of wide release has basically happened with the removal of Safety Score and Autopilot mileage checks although the user experience of needing to push the request button and checkboxes then wait isn't ideal.
There's just 10 days left in 2022 for Tesla reach these milestones of deploying single stack to more than a tiny percentage of vehicles and achieving actually wide release to the probably small percentage of vehicles that can't use FSD Beta yet (e.g., those who didn't want to accept the terms when requesting limited early access FSD Beta, vehicles with "too new" vehicle software, vehicles with older hardware like MCU1, vehicles that had too many FSD Beta strikes).
