NoAP is definitely not ready for prime time. EVERY single time I have tried to use it, it failed in one form or another. I can't always predict WHEN it will fail, but I can predict that it WILL fail at some point on every trip, just because it consistently has. TRUST is the key; if I can't trust it to perform consistently, then it is effectively useless. I have watched many videos of AP tests and ratings... the theme is fairly consistent... your can't trust AP to perform... sometimes it works (and the tester is amazed), then it fails (and the tester is disappointed). The point is, it only takes one bad fail to kill someone.
Elon insists that LIDAR is a stupid approach; cameras are all that is needed for spatial awareness.... but that is only true in ideal conditions Recently I have seen many videos taking about ways to circumvent issues when bad weather (snow/rain) blocks the cameras and the radar. REALLY..!?! I have seen the alarms come up when a camera is blocked (and I live in an area where snow is not an issue). Again, TRUST... if you can't trust it to perform consistently, then it is effectively useless.
I am waiting for h/w 3 to roll out in Canada. Artax rolled off the assembly line a week or so before h/w 3 became standard. I do believe that some of the issues I have observed are related to the delays due to h/w 2.5 processing power. But I am not holding my breath that h/w 3 will solve many of the problems (certainly won't address the blocked sensor issues). Again, I have watched videos of testing post h/w 3 upgrade; although there are improvements, still way too many fails.
For me TRUST is key... so I don't see NoAP being anything more than a novelty. As a novelty, definitely NOT worth paying for... at ANY price. I wouldn't pay for it again (too bad I can't get my money back). In fact, with other vendors introducing alternatives with competitive range improvements, not sure I would buy Tesla again (if s/w is no longer a driver, and range is competitive, the only other reason left to buy Tesla is Customer Service... and we all know Tesla customer service SUCKS).
