We have a 24 model Y and the software update about 3 weeks ago made a huge change for the better inFSD. Before that it was largely a neat toy but not really usable. Nice that update it has some value. Still would not trust it on winter roads as it does not slow down until entering the corners and does not slow down coming into towns when the limit goes down. It does nice passing on the interstate now. 

We have had this one since mid June and have about 17000 on it with no issues.
