I think a better or more simple answer is either a scantly clad women walking or jogging, or a minor accident causing unnecessary breaking resulting in a jam.

Scantly clad woman jogging...

...justifiable slowdown.

I believe that I saw work done ages ago, I think by Germans, on this type of effect backwards on traffic. It's at least 3 and maybe 6 years ago, or even longer.

Many traffic jams leave drivers baffled as they finally reach the end of a tail-back to find no visible cause for their delay. Now, a team of mathematicians from the Universities of Exeter, Bristol and Budapest, have found the answer and published their findings in the journal Proceedings of the Royal Society.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2007/12/071219103102.htm"><P>The model predicts that this is a very typical scenario on a busy highway (above 15 vehicles per km).
