From Why Your Team Sucks: The Philadelphia Eagles, reader Marchman says,
I have no real idea why Philly drivers would be notably terrible but they’re by far the worst I’ve ever been around. Chicago drivers are dangerous lunatics, but they’re predictable in their aggression and rage; Philly drivers are terrifying because they’re totally unpredictable. I routinely see people driving in two lanes at once, driving and parking on the wrong side of the street, driving and parking in bike lanes, turning with no signal, etc
I think Marchman is Doug DeMuro’s next-door neighbor.
