Commentators on transportation policy sometimes write as if drivers and nondrivers are locked in a zero-sum game- that is to say, what benefits one group always hurts the other. For example, I recently read a book that repeatedly referred to public transit and other pro-nondriver policies as “anti-automobile.” But after driving for a year here in Jacksonville, I have discovered that policies designed to speed up automobile traffic are not good for all drivers all the time, even if they are bad for nondrivers.
