I've lived some places where 4-way stops were just abused, like Sugarland, TX. England and Ireland are full of roundabouts, some of which are incredibly small, just a painted dot, and some are giant multi-lane white-knuckle nightmares. There are places with good traffic light setups, but traffic lights generally suffer from the same problems of sometimes stopping traffic for no good reason while also encouraging excess speed.

In my current city, I can identify at least 3 intersections that would be better as a roundabout, but I don't have my hopes up.

Yeah, I know what you mean by abusing 4 way stops being abused. Thankfully I moved from there a long time ago.

Also where I moved from recently, they changed a roundabout intersection into a traffic lights intersection. And the traffic used to flow. Now it’s a stand still.

There’s always so many little insights when you use the road daily that a planner will never have unless they do the same.

Melbourne where I am kind of close to now, has an absolute clusterf*ck of overpasses, underpasses, toll ways, free ways, tunnels all coming & going out of a neatly planned grid. They probably think it’s planning perfection while driving it as a non-resident is an absolute nightmare. Sydney which is famously poo poo’d for not being planned in Australia is 10x more straight forward to drive.
