The key to understanding the incoherence of the auto-centric libertarian is to recognize that they equate the automobile with individual freedom. In that mindset, when the government spends money increasing the amount people drive, they are simultaneously increasing individual freedom, which in their eyes is the primary role of government. They will join in condemning boondoggle projects and pork-barrel spending, but they accept, and often promote, highway expansion as the proper role of state and federal governments.
