Demonstrably incorrect on my street, which has hotly contested on-street parking that narrows the roadway to a single lane. Cars have to stop and reverse into parking spaces to pass each other. Yet children play ball games in the street, and stop to move out of the way of the cars, with the cars barely needing to brake.

Children are not mindless suicide machines; they learn at a tremendous rate from their environment. The children you see around you might not survive on my street, but that's because they haven't lived there for all of their lives.
