I guess you are one of those who say, glass is 1/100th empty?
For me it works, and it is true I am guessing for over 90% of Tesla drivers. I will take that.. There is always for someone somewhere it doesn't work.
No, I'm the type of person that says, "Hey cool.
@Electroman has a glass. My glass has holes in it, so it's still a glass but it doesn't hold water as well as his".
The fact is, NoAP works fine if you live in an area of the world where highways are extremely simple and the land is flat. That's great. But if you're going to say NoAP works 90%, then I'm going to produce stark counter examples. Two weeks ago, when I got my latest update, I took the car out for a ride on a route that has traditionally had trouble. That route is less than 200 miles, and it's go everything from Interstate to state highway, multi-lane roads to twisting back roads. I can easily reproduce the same exact type of error, in the same exact place, every single time I drive past it. Not almost every time, I'm talking 100% rate.
In the cases where I don't force NoAP to do the right thing by tapping the accelerator or taking the wheel, it will come to a nearly full stop or swerve dangerously. Again, not some of the times I drive through these scenarios, but 100% of the time. If I was do these tests when there is traffic, it would create a very dangerous situation for anybody around me. That's not FSD. That's nowhere near FSD.
Now, I'm willing to accept that Tesla could produce a system that covers 100% of your needs by the end of 2019. I'm even willing to accept that they could produce a system that eliminates all of the scenarios that fail for me by the end of 2019. But to imagine that they will have trained their NN to the point where it can be considered Level 4 or Level 5 by the end of 2019 is something I can not do. As Elon notes, the real world is too messy. There are too many things that they will not have trained the network to understand, and that fact alone means they will not be able to provide full autonomy.
