I got a free month of FSD 12. Since FSD 11, while not perfect, was pretty useful when we had a 3 month demo, we gave this one a try... well, it hit a curb where FSD 11 was never had a problem. My fault not reacting quicker, but still.
There was so much hype that it was so much better. In my opinion, it isn't. Not it New England suburbia anyway. The way car behaves makes it less predictable and more annoying than FSD 11 was. YMMV.
