I had to pick up Sarah from school today because she missed the bus. On the way out of the parking lot, there is a
roundabout. I yield to oncoming traffic, and enter the circle behind a truck. The guy on the right just zips into the traffic and almost hits me. Now, I have worked like 26 days in a row. I'm tired and cranky. I honk and yell at the guy and he continues to move into the circle. "It's a roundabout, you have to yield!" I yell at the moron. Honks and yells back, "Hey, it's a roundabout - it's one at a time!"
Really, one at a time? One at a time in a roundabout? Explain that to me. How would that be executed exactly? If four cars came to the roundabout at the intersection at the same time and all wanted to go say, south - would every one stop until everyone else went south? It doesn't make any sense. His CYL (Car Yelling Logic) is flawed.
And by the way, even if he had no idea how a roundabout worked - THERE'S A YIELD SIGN AT EVERY ENTRY POINT! Yield does not mean "one at a time."
