Sidewalks found in suburban sprawl are purely decorative. Only the very unfortunate walk there because everything is miles apart from each other, making a car mandatory. Meanwhile, even super-dense cities, where walking is obvious, have to fight the ridiculous notion that cars deserve 80% of the street right of way and stupendously subsidized street parking.

No, sidewalks in suburbia are super useful for walking between houses. They're not useful for shopping or commuting, but they let kids walk to their friend's house to play. Not every trip is a commute downtown.

But then the paedophile can snatch your child into their convenient motorized kidnapping vehicle!
