The 2018.10.4 update is getting everybody excited about Autopilot again. I'm wondering if @jimmy_d, @verygreen, or anyone else who has a deep technical understanding of how Autopilot is evolving cares to speculate on what we'll see next. For instance, I watched a 2018.10.4 test video where the driver found that the car could handle any curve except on 1) especially sharp curves where it 2) didn't slow down ahead of the curve. Do we have any indication of HD map tiles for sharp curves that could be used to tag these curves and give the car an indication to slow down? What's happening with stop sign detection? Any insight on that? How is Autopilot now able to recognize lanes without markings, or improvised lanes made of pylons? Is this based on recognizing driveable road surface and non-road surface (e.g. grass, sidewalk) or undriveable road surface (e.g. the oncoming lane)? Does the new neural network architecture mean we'll see exponential progress toward full self-driving? Or is that just Elon and other Tesla execs overhyping the tech? These are just examples. I'm interested to hear what other people find interesting or are pondering.
