I walk commute often, and especially when I'm traveling. Sure, cars are dangerous, and bicycles are often irresponsible, but pedestrians are the worst. They'll walk four abreast, gather in large groups at chokepoints, block traffic to take photos, stop for no reason. And no one really cares because most of this bad behavior is limited to sidewalks, so it only affects other pedestrians. But it makes it damn difficult to walk at a decent clip. I'd really love to see "walking lanes" introduced, like bike lanes, for people who are actually walking and not treating the sidewalk like a goddamn park. </rant>
