Just a quick story to add: My husband and I were on a road trip and it was his turn to drive. So, I fell asleep for 1 1/2 hr. When I woke up we were passing the same exit we were at when I fell asleep! Yup! He had become so lost and confused we literally had reached the same place I had fallen asleep. Talk about a Twilight Zone feeling!
For the other side of the coin: I can easily go two or three times around these roundabouts before I figure out which road to take! :dontknow:
