The purpose of transportation is efficiency.  Users of transportation, besides expecting efficiency, also expect to complete trips safely.  Both attributes are products of competence.
Government as provider of infrastructure to facilitate efficient transportation also regulates who drives and how in vain attempts to create safety.  In order to insure the largest possible pool from which the Petro-Car-Tels can fish profits the government sets standards of performance that are no more than codified incompetence so that hardly anyone is denied their patriotic duty to consume.
Thus we have traffic jams unrelieved by infrastructure or public transportation and an insane death toll that proves the ineffectiveness of regulation as guarantor of competence.  Fiddling with traffic lights, expecting courteous behavior and adding busses is hopeless.  And until LTD provides ways for riders to get from neighborhoods to bus lines and back people will stay in their cars.
