Given all this consternation about our existing roundabouts, I'm advocating we change them to the style in this picture. This is called a magic roundabout in the UK. If you want to go three-quarters of the way around, you just use one of the mini-circles to transition to the inner ring which rotates opposite the normal direction of the outer ring. Thus, you only go one-quarter of the way around in the opposite direction. Easy peasy. Think of the efficiency and the fuel savings. Let's just put these in everywhere, and it will stop all the complaining about our present roundabouts.
