17.26.17 was pushed to my AP1 car late last night and I got a chance to drive about 130 miles with it this evening and from my preliminary observations it seems to be a nice improvement. Before this I was on 17.24.28 which seemed to be a bit of a step backwards. To me 17.24.28 seemed less stable and I had a couple of instances where it appeared not to detect cars that were stopped in front of me (it’s possible that it would have detected them eventually, but it started to get closer than I was comfortable with, so I turned off autopilot). But my previous software did not seem to have this issue. There are several bridges on a highway that I often travel where the pavement turns from asphalt to concrete and 17.24.28 would consistently lose the lane lines while going over these bridges. The previous version did not have this issue. I’m happy to report that 17.26.17 appears to have resolved all of these issues for me. It seems to be much smoother overall and there is one reasonably curvy road near my house that 17.26.17 now handles nearly flawlessly (it seemed to get very close to the center line a few times), but all of my previous software versions would have trouble with this road and often completely leave it’s lane unless I took over. 17.26.17 seems to detect cars stopped ahead of it much better than what I was seeing with 17.24.28 and possibly even better than the previous versions of the software, and finally I had no trouble with it losing the lane lines on the concrete bridges that 17.24.28 had so much trouble with. I’m sure I’ll have more thoughts as I use it more over the coming days, but certainly for now it seems like 17.26.17 is a good improvement.
