My favorite example of this is something I saw in a local bicycle planning study. A 4 lane stretch about 6 blocks long was converted to 2 lanes with parking and wider sidewalks (with the idea that people will naturally drive a bit slower with less of the street devoted to traffic). Someone was livid that it had happened, ranting about delays at the light on one end of the stretch. At busy times, the typical wait at the light is for the green (so not even a full cycle). Very occasionally a couple of cars don't make the busiest left on the first green.
