There is an intersection I take that they recently repaved but had not repainted all the lane markings yet. When you approach the intersection, the two lanes become left turn only and there is a third right turn only lane that appears on the right side of the road. There are overhead turn only signs but the right turn lane did not have lane lines. FSD Beta 10.3, 10.4 and 10.5 would get confused. It did not seem to understand that the space on the right was a lane. It would not move over to the right turn lane or try to move over too late or start to move over and then swing back. But today, they finished repainting the lane lines and there are now clear lane lines for the right turn lane. I am happy to report that FSD Beta 10.5 handled it perfectly. It detected the right turn lane and smoothly moved over when it was supposed to.
This result should not be surprising since we know FSD Beta is vision-only. Obviously, it will perform better when lane lines are better. I think it shows that some poor performance of FSD Beta could be caused by poor road markings. It might also explain why FSD Beta works better in some geographical areas. Those might be areas with roads that are maintained better.
Just wanted to share this good report. I think it is clear proof that good lane markings make a huge difference and definitely help FSD Beta.
