I have never understood why so many people dislike rotaries (some call them roundabouts or circles)
It isn’t hard: Cars entering the rotary yield to cars in the rotary. That’s it. They can be efficient, and even fun.
In a rotary navigated by people who know how to do it, traffic can usually flow well. Big, double lane rotaries can be quite difficult under heavy traffic loads, because in addition to knowing to yield to vehicles in the rotary, you also have to recognize how to approach your exit out of the rotary. If you are on the inside and don’t properly plan your transition to the outside (to exit the rotary) it can become a hot mess.
At least three times in the last ten years I have seen an elderly driver go the wrong way in a rotary.
Roundabouts are great. I like them with one exception. There’s one in Maryland where the roundabout starts and immediately the ramp to a northbound highway is there. when you are there the first time and are concentrating on the ramp to the right, you may not realize that you’re getting onto a roundabout and might just cut off a member of the local constabulary that you didn’t see, who turns on all kinds of pretty red and blue lights to ask you kindly to stop so he can let you know of your malfeasance.
Don’t ask how I know, but it ended with some laughs and a handshake and no citation.
