	I too try to damp out the stop and go of traffic however, rather than
limiting myself to freeway traffic, I also do the same thing in rush hour
in the city.
	The phenomena you describe is well noted and seems to appear on most
if not all freeways during rush hours.  In Vancouver B.C. on the 401 going
into the city, the traffic helicopters will report 'GHOST' traffic jams.
They can see these things from the air. Apparently, the "GHOST' moves along
the freeway and does not stay in the same place.  However, the "GHOST" seems
to remain until traffic thins out.
	As for the reason, I've no idea but am most curious.
