Yeah I think the web is more a tool than anything else nowadays and it being homogeneous is a good thing.

Think of roads. It’s one of few things that humans have managed to agree on across the planet and there’s a good reason for that. The system (regardless of which side you drive on) works. Signs, markings and materials are all pretty much identical wherever you go.

Hmm. The design of left turns on "stroads" seems to vary in the US. Mostly left-turn/U-turn lights in California, loop arounds in suburban Detroit, unprotected left turn lights in Kentucky, differs if the route is a national, state or local road etc.

On the other hand, right turn on road now seems to be universal unless a sign prohibits it. And all states apparently enforce slowing down or moving to the adjacent lane for stopped emergency vehilces.
