I love how people say "abolished" so easily and don't realize the magnitude of change it would require. /aside In any case, Arizona has a LOT of roundabouts. They take considerably more land so it would basically be impossible for the vast majority of existing in-city street corners. Arizona uses them more in rural/not yet developed areas. Definitely help speed up things, but I would say at this point, it will only be useful for new, very spread out cities.
