It has nothing to do with technology to make a car.
It is about how you design the environment that surrounds cars.
Washington, D.C.'s new ball park does not have many parking lots. Instead, it provides a free bike valet, enhanced nearby subway station, and a ton of bus service. They also ran an advertising campaign asking people not to drive to the park.
On opening night, 21,492 baseball fans (out of a total of 25,000) took a train to the ball game!
This is exciting.
