Pau Krugman: Friday Night Music: Sprawl, Again:
Consider the following thought experiment: you are driving on a road — let’s arbitrarily call it Interstate 91 — and must choose a lane. Traffic is so heavy that you can’t really change lanes thereafter. But there are many bad patches along the road; half of the distance can be covered at 60 miles an hour, but the other half only at 15. You might imagine that your average speed is halfway between 15 and 60, but… your average speed is only 24 miles an hour… you spend four times as much time watching the other guys race past [as going 60]. And this creates intense frustration and anger, a sense that it’s grossly unfair that you are in the wrong lane…. But it’s a good thing I didn’t ride the train (which for complicated reasons wasn’t an option); after all, that would have diminished my individualism.
