These Americans Are Just Going Around in Circles. It Helps the Climate

I hope they have signs telling out-of-towners how to use them, i.e. yield to cars already on the roundabout, enter the roundabout without blinking, and just before your turn-off, blink right to let others know you're exiting there. IMO The best would be signs several hundred meters away, maybe with 1 "lesson" per sign.

Even in Europe the rules aren't consistent, the French think they have to blink to indicate their turnoff as if there's no big circle in the middle of the road, but the issue is if there's a roundabout (counter-clockwise) with four exits and entrances (say north, west, south, east) and I'm waiting to enter from the north end, and I see a car blinking left, how do I know if that car came from the west wanting to exit north (which would mean I'm free to enter the roundabout because I'm not going to cut it off) or if it came from the east wanting to exit south (which would mean I have to yield to it). If someone else is going south to north and isn't blinking at all, how do I know if he maybe is going straight east to west, or is too lazy to blink? North me would have to wait until it exits (or pass me) before I can enter, wasting my time.

My other pet peeve is people who don't blink as soon as they can: if you want to exit north, once you've passed the east entrance you can start blinking, this lets people waiting at the north entrance know they're free to enter the roundabout. There's a major road I sometimes drive through, and they have 2 roundabouts where there's always a wait because idiots blink a millisecond before (or in a BMW or SUV, after) they've turned off the roundabout, making people wait.

It seems that swapping out n-way stops for circles is almost always better, unless they have signals on them IMO. Or unless you have the circle turduckien one Swindon.
