From this months free trial, it does seem very good where there are lane lines. It does a great job of staying in lane, following GPS, switching lanes to pass and exit. It’s great for highway use, and I could believe it may be better than humans
Local roads around here usually only paint the center line and FSD gets closer to the edge than I’m comfortable with, although I don’t give it a chance to see if it’s actually dangerous. Similar to crossing an intersection: on my way to work I have one where the other side of the intersection is offset and there is no lane lines, so it changes lanes in the intersection. Oops, but also bad road design. Plus I have had it make a couple wrong choices when it can’t see but I can.
