Re: Missing the obvious
"It has poor road markings"
Considering the state of road markings on even some quite major roads here in the UK, especially since all the council cutbacks kicked in, I, as a very experienced driver doing about 45,000 miles per year, sometimes have difficulty working out where the lane marking are, especially in wet conditions at night. Computer "vision" is really not all that good yet so I'd be not at all surprised if an AV ends up in the wrong lane or even straddling lanes in those circumstances.
