There's one bike-and-ped bridge I used to cross for work, and as a cyclist I did find pedestrians very annoying--they take 90 degree turns across the trail without looking at all -- but that's only one very crowded section. (and as a pedestrian, the cyclists were never a problem for me there.) But that's one crowded bridge. On most roads, people walking in the roads instead of the sidewalk wouldn't matter to me. You could 10x the number of pedestrians and it'd be fine in most of my city (Austin TX). Maybe that'd change if it were pedestrian-friendly and we ended up with 50x the number of people walking, but this is a problem I dream of.
