Earlier quoted context omitted.
Public transportation is quite good in Europe compared to say, the USA, where car companies purchased intranational train tracks, dismantled them for highways http://en.wikipedia.org/wiki/General_Motors_streetcar_conspi...
I suspect Europe's population density being 3 times that of the USA doesn't hurt either.
The low density of car-oriented US suburbs was mandated by socialist central land use planning from Washington and the motorcar industry that wanted to require Americans to each own a car. Standards were written centrally and local governments were required to make them law with grants, national bank regulations that required them for lending, and professional standards organizations that made civil engineers agree to them for licensure.
The more market driven land use in European cities promotes walking and transit more than personal motoring.
