I have two Model 3's with EAP/HW2.5. NoA is unusable and always has been. It requires user intervention at least every 3-5 minutes while on the highway to prevent it from doing something stupid. It has no planning or executive capability.
My reasoning has always been this: If NoA can't be made to work properly on controlled access highways, which is the easiest scenario in driving, then FSD on surface streets, which has the added complications of traffic lights, stop signs, pedestrians, construction, stopped vehicles, etc. is not possible. Properly working NoA on highways is a necessary prerequisite for surface streets FSD, and the prerequisite is not even close to working.
I have a new Model X on order, I ordered it without FSD because the system is useless. When it's actually working at level 4 or higher (or at least level 3 on highways -- i.e. >60 minutes between interventions with at least 10 second warning before an intervention is required), then I'll purchase. But I don't have to worry, my Model X that isn't even delivered yet will be 10 years old and in need of replacement by the time that happens.
