"Where to go once you are in a roundabout"

Just out doing some night photography and I took this time lapse shot in a roundabout just to see what kind of streak lighting I could get with a 15sec shutter speed and a 22 f/stop setting. What I really learned is that it is sadly true..........people actually do get confused, stuck in their tracks and don't know what to do when they enter a roundabout! I thought it was all a joke until I witnessed it myself in fact one guy actually missed his exit and started to back up (most likely his wife was with him and offered some helpful advice) and then proceeded to go one more time around until he could exit. It was amusing! :)
