Just don't draw any lines and even on wide (>2 cars) roads people seem to hug the center pretty naturally (IME, there are probably cultural differences between how people drive in different places that matter here).

The strange part about this road is that there were so many lines by the edge of the road, that's legitimately pretty confusing. I'm not sure if it's confusing in an unsafe way, but it's definitely uncomfortable.

I'd love to know if someone has a link to someone knowledgeable comparing "all these lines for edge lanes" to "just don't draw anything".
