I honestly don't see how this could be described as "nearly flawless" by anyone anywhere.
I can't even get it to make sane decisions on any local highways in any of 3 different vehicles. This behavior was mirrored when trying on California highways as well. Seriously, it generally can't perform well enough for more than a couple of miles in most cases without intervention (not even counting the useless need for torque on the wheel before it will
do anything at all). And I'm not just talking about intervention because it's doing something kind of silly, pointless, or just dumb. Those are plentiful for sure. But, I also mean intervention as in, if I don't prevent what it's wanting to do there may be an actual accident involved. So far, it's not been anywhere near flawless in any situation for me or anyone I personally know.
@clydeiii Really, though, if you can do a 25 mile commute with NoA with minimal interventions, and minimal overrides (like, letting it make and proceed with the decisions it makes to change lanes, interchanges, etc), I'd honestly love to see that in action if you get time and inclination to make a video... like, where the AP/NoA status can be seen in the video the whole time. Will be disappointed if this is on an empty road with no lane changes, or at below traffic flow speed, though.
I think you may be singing some higher than deserved praises when looking at it objectively, but that's just my guess based on now thousands of miles of experience and attempted use of this feature over multiple vehicles in a wide variety of locations.
