I firmly believe that every honest person admits that automobile
transportation can never be a model for worldwide transportation
planning.

The planet cannot support that many cars. Period.

I heard that China is pursuing an aggressive campaign to build new cities at an alarming pace. With the global warming already
occurring just from current auto use (a part of Antarctica's ice shelf just splintered into ice bergs recently,) the addition of a 250 million new cars would be unthinkable, especially given the poor record China has in environmental preservation.
