Are roundabouts really more efficient–meaning do they handle a larger volume of vehicles than other means of traffic control such as stop signs or red lights? Intuitively, I think we all know this is true. But intuition is not always correct.

So thank goodness for MythBusters! We recently became aware of a MythBusters episode where they take on the “myth” of the efficient roundabout. Want to guess what they found? Obviously, we wouldn’t be talking about it if it didn’t confirm our intuitions 🙂

Yet, the show is very entertaining and definitely worth the 10 minutes it takes to watch it . . .
