Roundabouts

Who decided that four roads coming together now deserves a round-about instead of a stop sign? I have spent more time behind people struggling to go in a small circle than I have spent time in line at the grocery store in my entire life. This is ridiculous. First of all because they are a waste of money and stupid, but more importantly because people seem to have trouble going in a circle. From now on there should be a associate from the DMV seated in the middle of these things and if it takes a person more than 10 seconds to make their way through they should have their tires shot out and licence revoked.
