They’ve got an actual 2-lane traffic circle out here, it’s quite busy, not very well lit, and, I’ll admit, I’m a little uncomfortable running through one of these in the dark.

@LoneLocust This seems to be one of those divided by a common language days… Is a 'traffic circle' a roundabout?

And by two lane you mean you can go round it in either direction? We have got one of those. It's in Swindon, and it’s a little more complicated than the on in your picture... https://hillsideherald.com/to-do/the-magic-roundabout-in-swindon/

The Magic Roundabout in Swindon - Hillside Herald

Tucked away in Swindon, Wiltshire, the Magic Roundabout is more than just a traffic junction—it’s a local legend. Since opening in 1972, this quirky

@simonwood I think there’s an awful lot of crossover between the two. I believe traffic circle is the current preferred term in motor vehicle engineering circles and traffic circles allow for more forms of traffic flow control than roundabout does. For example, you could have stoplight limiting access to enter a traffic circle, whereas I believe roundabouts exclusively use “yield to oncoming traffic” flow control.

This particular one was actually just yielding.

@LoneLocust I'm pretty sure we have roundabouts with traffic lights (which I assume is a 'stoplight’) over here. I've not come across the term “traffic circle" before.

@simonwood and by 2 lanes I mean that there are 2 lanes entering the circle and going around. 1 on the right where people exit and 1 on the left where people just go round forever, but the idea is you’ll eventually merge outwards and then turn right and exit the circle.

There are so few Arizona that most of the ones we have (and I can think of fewer than 10 in a conurbation of several million people) are single lane and on small neighborhood streets.

@LoneLocust Oh we have lots with two (or more lanes) in the same direction. They are not so terrifying.

@simonwood Oh, now just imagine that absolutely NO ONE going around the circle has ever been told or shown how to drive in one AND, 50-75% in the circle have probably never seen or been in one before.

They're terrifying.

@LoneLocust If you really want terrifying… have you heard of ‘priorité à droite’?
