They have since fixed the worst ones. In all fairness, it probably worked OK when first installed but traffic volume increased dramatically.
Current state of rotonda on second ring is much improved; traffic lights now stop at entrance.
I seem to remember what may have been an urban legend about a British couple who just cracked up laughing when they came upon a traffic circle in the U.S. where someone had put stop signs on the actual circle. I'm thinking that would be even worse than lights because no one would know when to go.
