Got the notice overnight for our late '23 MY, installed early this AM.
Have not had any trips with FSD 11 without many disengagements for the same host of reasons others have had.
Yesterday afternoon was the last straw, and as I mashed the voice feedback for the "what happened?" notice, I screamed what happened was I don't have 12.3, that's what happened, and it's driving erratically, and I need 12.3! I'd like to think that's why I now have 12.3. My story, and I'm sticking with it.
One trip to pick up groceries and it was a mixed bag. MUCH, by far, better than earlier releases, but same speed issues as others noticed. A few bad lane selections which I had to interviene for, but so far impressed. Will have to make a few runs non highway where I always used FSD before to get a better feel for 12.3.
But overall, with just one drive, very impressed.
EDIT: typo's
