I’m in Middle Tennessee and they have put a few round about in the new subdivisions. I love roundabouts being I spent a short time in England in the Air Force during the cold war. Another good thing about roundabouts is that if you have a vehicle that is prone to be on the boarder line of overheating your more apt to not have it overheat in an area with roundabouts vs stop lights being most of the time the your vehicle is moving getting air flow across the radiator. I live in Murfreesboro, Tennessee were the traffic is horrendous almost all the time during the day, and very terrible during rush hour, alot of stop lights you have to wait through two cycles before you get through, it really gets old. Roundabouts in this area would really help out a lot but it would really be expensive to put them in, and that is not going to happen. anyway if you don’t like traffic don’t move to the Nashville/Middle Tennessee area with all the various bedroom communities/cities you will hate it.
As far as I know we have no round abouts in my town, but if I am not mistaken there is one at
Fort Campbell, Ky in the housing area on the Ky side.
They aren’t so bad IF you re NOT towing any kind of trailer-—horse-—boat-—water ski, etc.
Otherwise, they are a nightmare.
