When you folks say "got the push" you just mean you got notification to download, right? Or has your car been updated without you doing anything to trigger the installation of V11?
I don't have wifi at home so can only download deliberately when I go to a place with fast, public, wifi in a parking lot (I go to my Tesla SC). But there have been at least 2x that Tesla has pushed an update to me over LTE, so I've arrived at my car in the morning with notification that an update has been installed.
Because this update is moving even non-FSD customers over to the new single stack for highway and streets, I suspect this is an update I'll receive whether I want it or not.
After putting off the Christmas update until Easter Sunday (cuz I didn't want to deal with yet another UI change), I got the download available notice for V11.3.6 on April 13th, so just 4 days later. I haven't done the download yet . Partly I haven't taken the time to do so (it is a 20 minute drive to the SC plus sitting there, plus I do the installs there which, the last one took 37 minutes) but also, AP works just fine for me and I don't want to lose something that is working in favour of something "new" and possibly less reliable. In particular, I'm reading that the audible warning for applying torque to the wheel has gone away and that is necessary for me since, when in AP with my two hands on the wheel and looking out the windshield, (in other words, being an attentive driver monitoring the Beta AP), I don't see the flashing blue screen because I'm paying attention to where the effing car is going at 110 kph. On Thursday, I got the audio warning under just those circumstances so gave the wheel a bit of a yank and avoided a strike. Without the audible warning, that would have been a strike for me.
On the other hand, since I think I'll be forcefully updated, it is better to do so on my own terms rather than try and figure out WTF the car is trying to do under the new AP (and confirm my old settings) as I'm rushing off to work at 6:20 in the morning.
