As for the stoplight at the roundabout.
There is a roundabout that was built in Rochester, Mi, one of
the northern suburbs of Detroit, about 15 years ago.
2 lanes in and 2 lanes out X4 and an extra right turn exit
23 stop lights.
I've never seen them turned on
Casually spending other peoples money seems common place
