It's hard not to sympathize with this everybody's an idiot view of our multifaceted forced interactions living in a city. But I think it's better to turn it on its head. Ever been a pedestrian? then maybe you can be a bit forgiving when you're out driving, and let the frozen foot-commuter have right of way at an intersection (which, you know, he's supposed to have anyway). Ever driven in Philly streets? then maybe you can be a bit understanding, as a bike, of the visibility limitations where there aren't bike lanes, and of the frustrations that drivers feel watching you sail through red lights. Ever been stuck in any traffic situation not of your own making? then maybe you can lay off that horn or take a pass on flipping the bird -- there's almost always a reason for the tangle, and you're unlikely to help by getting steamed.
We now return you to your regularly scheduled mid-holiday rants.
