Wasn't AP 1.0 supposed to be only for highway driving only - from on-ramp to off-ramp? Isn't that what Tesla has promised in 8.1, to use the navigation routing to determine when to enter & leave a highway?
I don't recall Tesla ever promising to provide intersection support with automatic detection of stop signs or stop lights - the sensor technology and processing power were never going to be powerful enough to handle all of the extra object recognition needed to account for the additional complexity of driving at low speeds or stopping at intersections and tracking cross-traffic, pedestrians and other objects you wouldn't see at highway speeds.
I don't have any of this in my P85, though we are planning to buy an AP 2.0 Model S soon (when the 100D is released), so I don't have personal experience with AP 1.0. But in tracking Tesla's announcements, it appears they are on track to deliver what they had promised with AP 1.0 - driver assistance from highway on-ramp to off-ramp. And while they aren't there yet, it appears they remain on target to deliver that in a few months (on Tesla time).
AP 2.0 customers are taking a bigger leap of faith if they buy the full self driving option - since getting that enabled will not only take major breakthroughs in Tesla's software, but also handling some major non-technical challenges, such as getting regulatory approval and working out who will be liable when accidents happen.
But, I'm comfortable with that, and when we order our Model S, we'll place our bet - order the full self driving option, and hope Tesla is able to achieve what is an extremely aggressive goal.
