@rowens unless you're in the northeast, where traffic circles are a hecking way of life
We got one of these and it makes my brain hurt https://en.m.wikipedia.org/wiki/Diverging_diamond_interchange
@pmosetc *blink* *blink* Huh. That's... something.
Re. circles, they're being incorporated into new construction here in Montana (started 3? 4? years ago, maybe more). Plenty of grumbling about 'em, and lots of folks still have no clue how to use signals on circles. OTOH, many of those same drivers think signals are optional at all times, so technically it's not a big change. Mainly though they just work, and traffic just flows, in spite of the naysayers.
