I have a 23 Model Y that does not have USS sensors. It updated last week with the new Tesla Vision based park assist. I have to say it works quite well. Not perfect but does an adequate job both front and rear for nearby objects.Scheduled pickup for my Plaid for tomorrow morning.. and whew, they have called me twice today about my delivery day to ensure that I know that there are features that will not be working for a few weeks.. (their words, "in the coming weeks"). I had to accept it in the app a week or two ago too.
