Stuck in Traffic?

Do you ever have those days where you just seem to be going nowhere fast?  After a day in the field in Mexico,  I was almost back to the border and ended up stopped in traffic.  I was surrounded by vehicles on all sides and therefore, got to wait it out.  Below is a Google Earth Image of the intersection I was waiting at (Pink arrows are traffic directions).  I was about where the pink spot is.  I wanted to turn at the blue spot and lots of people wanted to go where the green spot is.  People (including a big bus) started lining up for the green spot blocking the other three north/south driving options and then the north/south drivers filled in the gaps.  

It quickly turned into what looked like one of those games where you have to slide cars around in a parking lot to get one out, kind of like these  :-)  http://www.lilgames.com/highway.shtml or http://www.2flashgames.com/f/f-146.htm

How was this remedied?  It took a police officer coming and blocking off the green ramp before people would concede and take another route.

Do we ever find ourselves stuck (and maybe holding other people back) because we are determined to do something or maybe haven't considered other options for getting a job done?
