Is this a $1.2 billion dollar whim? Or is Obama planning to get rid of your cars?

The new focus on biking and walking represents a turnaround from the administration of President George W Bush. Mary Peters, transportation secretary under Bush, dismissed biking paths and trails as projects that "really are not transportation," saying they had no place in federal transportation policy.

In March, Mr Obama's transportation secretary, Ray LaHood, announced a policy "sea change" that gives biking and walking projects the same importance as automobiles in transportation planning and the selection of projects for federal money.
