Personally, I don't hate them. At least the single lane ones. Not too fond of the ones that have about 5 or 6 roads converging and have to keep track of which lane i need to be in. Nearby town has 3 now and working towards the 4th. They're fine, until Great Uncle Bob gets to the entry and stops, looking both ways over and over until such time as he can no longer see a single moving vehicle anywhere in his line of sight and f-i-n-a-l-l-y creeps out and then stops at each exit off the circle to be sure he still can't see a moving vehicle anywhere.
