Normal Traffic Future: Different Views

There is a nice panel discussion of the issues surrounding efforts to increase pedestrian and bicyclist accessibility in cities. Do city planners have to choose which side to take: pedestrian/bicyclist or automobile? Or is there a different way to look at it? It appears that many cities in the U.S. are pondering this issue. Normal is also taking steps (hah!) to increase pedestrian/bicyclist accessibility and is facing criticism and opposition as a result. Give up driving lanes or parking space on the streets so "a few" people can ride their bikes? Many seem to be saying "No!" to this. (What I find humorous but puzzling is the local animosity toward bicyclists that wear spandex -- what I call "spandicles." Are they hated for their clothing or their aggressive biking?)
