i didn't like the racer dude with the helmet; wrong message for bike signage. the 'bike' symbol without rider is less ambiguous IMO. The racer dude iconography was redolent of universal sign language seen at olympic venues in the 1980's.
I think the survey's intent was to gauge the effectiveness of sign iconography rather than looking for input on road accomodation design, as suggested above by some of the militant vc contingent.
