To call somebody "pedestrian" is condescending, but walking is the means of locomotion that human beings were designed for. Why do Americans walk less than people anywhere else in the world? Because they drive more. Before the obesity epidemic, there was a national movement already get us out of our cars and on to the sidewalk — even here in Los Angeles, the car capital of the world. The City Council might push the Department of Transportation in that direction. Urban designer Deborah Murphy is the founder of Los Angeles Walks and chair of the City of LA's Pedestrian Advisory Committee.
