My car has been on 10.9 since it was released. Its been my best experience to date. Yesterday, I got the updated Nav Maps but no other software changes. Afterwards, roads it used to drive fine are iffy and I've had to disengage. I was surprised by this. I figured the FSD driving functionality would come mostly from the cameras. I'm surprised the maps could have much effect. Sadly, it doesn't seem to have improved using turn signals or anything like that.
What are others experience with the map update?
