Yes, I took delivery on 8/6 and mine is still on 2020.11.105.1, yet half of YouTube is flaunting their newly unlocked blindspot/side repeater cameras and other features. This software is from April 2020, the car was built in August 2020, LRAWD, no FSD. The wait for software updates might be just as bad as waiting for car delivery.
I've learned that updates are released in phases with priority given to certain build groups/compatible cars before eventually trickling down. When Apple first started doing major OTA updates for the iPhone 4 and everyone downloaded it simultaneously, it crashed the network. They tried a phased approach only to have the internet rip them apart. Now everyone gets updates at the same time. I'm surprised Tesla keeps advertising revolutionary OTA updates when it's clear the updates do not hit their entire fleet in a timely manner (but technically eventually will).
