The worst is traffic lights. We have a crazy little 6-way intersection near my house, completely hemmed in by 250 year old buildings, that was only ever stop signs for four of the six legs of the wagon wheel. Always worked perfectly fine, until some idiot decided it was dangerous and had a traffic light installed.
Now, it’s backed up five to ten minutes in all directions, nearly all day everyday. Trouble is, with our prevalence of creeks and bridges, you pretty much need to go thru that intersection to get anywhere.
We have two rotaries nearby, and they both work great. Yeah, you often have to pause a few seconds on entry, but that beats a line of a half dozen cars at a stop sign, or a baker’s dozen waiting at a red light, every time.
