LOL. The roundabouts I saw at my uncles patch, in northern UK were huge things, like 1000' diameter. Locally, they installed the very 1st 3 x roundabouts aprx 15 miles north of me, by the airport. All 3 are tiny things, like 75' diameter. 2 of em are joined together, like a figure 8. Stupidest setup you have ever seen. 9 accidents in the 1st week it opened. And 4 x side roads branching off of each round about. Ill conceived..not engineered. The last time we had a round about was the late 1940's and mid 50's...downtown, where 5 x major roads converged. Folks didn't know how to use it..they ripped it out, and went to a multi intersection traffic light set up. Round abouts here are all CCW of course.
An Aussie naval officer is over here in western canada on some training program. Gets off the plane and immediately rents a bmw. 45 mins later, he crashes into the side of my bro-in law, sister, and mum.
