The three lanes of the road.
As a truck driver in Sydney, there are some older thinner roads where it's better to stay in the far left or far right of the lane, to avoid problems or relax, knowing that I won't have any problems. Cars seem to not need to think of it so much. As Full Self Driving (FSD) becomes a thing, those vehicles may need to also utilise such a break up of a single lane into three or more.
What are your thoughts on this?
