I have seen a lot of Tesla Owner Youtube Video's that disproves this. Of course since I have not received my car yet I have zero personal experience. Maybe if you had said "can't take all curves at any speed" might be more accurate.
Sorry, yes, taking curves at speed, I'd edit the post, but this forum doesn't let us. However, show me a video at slow speed of AP2 working on an exit ramp curves, doesn't exit because the HW can't do it yet. Also a lot of the youtube videos are AP1 and not AP2.
