Automobile and Public Transport Externalities: USA

Economic externalities is a contentious issue in transport. One side, reflected by the data below, attempts to establish prices to estimate impacts of the automobile that they believe are not sufficiently quantified by the economic system. The other side, which includes The Public Purpose generally opposes any attempt to establish policies based upon administratively or academically estimated prices, since, as Nobel Laureate Frederik Hayek put it, the market price cannot be known outside of the market.
