You are not factually incorrect, that there is still work to be done. And that will be true for the next 20 years. There will be a scenario that it will find difficult and disengage. This is the difference between someone who is perennially unsatisfied with anything, a Debbie downer who fails to see progress - and - someone who with a positive outlooks that says, 'hey this can drive me around in 50% of my routes and the rest I will drive (for now)'.
5 months ago there was NO car anywhere in the world that customers can buy that will drive itself and take right and left turns, go around roundabouts, go around double parked cars, get into the parking lot and stop in front of the destination. Today we have one that does that for most straightforward situations but struggles in many road conditions that are congested, poor visibility (for turns), confusing lane markers, incorrect map data etc.. Sure but if it works for 50% of my trips with the hope that the other 50% will gradually work over next several months and years) - that is HUGE plus. For those in NYC and downtown SF, that is probably only 30% of the routes that work. For those in Dallas, San Antonio, Phoenix and many many other sprawling cities and suburbs that ratio is much higher. Maybe as high as 70%.
Anyone that can't see this as a great progress that is useful for many people in many situations today, need to get a reality check.
I have seen this same whining when AP was first introduced. Oh, it can't do this, it can't do that. But AP even in its first iteration was a great life saver on long slow highway commutes. It was God send for people like me who sat on traffic one hour each way, everyday.
