2016 S90D HW2/AP2-Finally-just went to 17.26.76 from 17.17.4 Overall, smoother, but not yet "Silky Smooth". I give it maybe "Nylon Smooth". Took 27 minutes to install via WiFi. Immediately took it in a 60 mile run. Better on Freeways, and better on lower Highways with turns. Surface roads are greatly improved....except....It seems to have a bias, to the left, toward the oncoming lane. It even shows it a bit on the display. It ventured into the "Bots Dots" marking the lane a bit. It seemed to "anticipate" the turn better, and was smoother in the entire turn. It no longer drives like a drunk-just slightly inebriated. It did stop, rather tentatively for a car that was fully stoped way in front of me. It didn't stop as early as I would have, and my foot was hovering over the brake pedal.
I did have 2 "phantom" hit the brake moments. The situations were understandable. One I had to press on the accelerator, and it got me thinking about a safety issue. If your foot is close to the Accelerator pedal, and the car decides to brake, there is a chance you might override this accidentally. If the car brakes hard (phantom os real need) your personal forward momentum could cause you to override the braking action. Once you touch the accelerator, the auto braking disengages. This is good in phantom braking cases, but could be problematic in real, needed, auto braking situations.
17.26.76 does not read Speed limit signs at all.
I had logged close to 20,000 miles on AP1 and this is getting close, but not yet.
I remember the early days of AP1, when the car would dive for most off ramps. AP1 is great now, but it was hardly "Silky Smooth" until many months later.
I am encouraged by this update. When you think about it they went for zero Autopilot 2 capability last October, and now 6 months later AP2 is pretty close. AP1 took one year to get Autopilot 1 running, and that was with the help of MobilEye, that had been doing this for years.
OK-Time to wait impatiently for the next update....and the Model 3 delivery on the 28th.
