You are driving along the interstate at a comfortable 75 mph when a car passes you going above 80.  Behind it are two or three other cars trying to keep up.  Without thinking about it you find yourself accelerating to keep up with this group.  You have just been pulled into a speed vortex.

I think Speed vortexes are caused by a subconscious urge to either compete or belong.  The entire phenomenon needs more study.  A speed vortex is most likely to pull in like vehicles.  A small car speed vortex has less pull on SUVs.

Have you ever been pulled into a speed vortex?  Isn’t it nice to know that it now has a name.
