I know Europeans love roundabouts but Americans don't know how to use them. I hate 'em and avoid them whenever possible. There's one near the main drag of the popular MUP and if there's even a single vehicle approaching the roundabout you can bet the driver will manage to screw it up.
There are some older roundabouts in my area that are even worse. I'm sure the designer thought it would be an artsy way to spice up the old historical neighborhoods and maybe control the traffic. But it just makes things worse.
And if roundabouts really worked in Europe they wouldn't be resorting to these indecipherable paint schemes that supposedly "help" direct motor vehicle, cycling and pedestrian traffic. If the physical infrastructure doesn't already solve the problem, paint ain't gonna make it better.
