Typical Tucson scenes: A woman taking a walk pushes her baby in a stroller along the side of a residential street.
A man in an electric wheelchair rides up the bike lane alongside speeding cars on a busy thoroughfare.
Young boys and girls laugh and clown while walking in a street on the way to the park.
All these people are in the streets, in harm’s way, because of a historical mistake: Tucson didn’t require sidewalks as part of housing developments during decades of growth after World War II.
