In what sounds like a terrifying experience, the girl’s elongated form appears to rise from the ground as cars approach, reaching 3D realism at around 100 feet, and then returning to 2D distortion once cars pass that ideal viewing distance. Its designers created the image to give drivers who travel at the street’s recommended 18 miles per hour (30 km per hour) enough time to stop before hitting Pavement Patty–acknowledging the spectacle before they continue to safely roll over her.
One question: What children play in parking garages with a rubber ball? A neighbor, maybe, but not a garage. Tom Vanderbilt doesn’t like the idea on the grounds it might lead to people swerving instead of slowing down, and hitting other cars, objects, or, sadly, kids. Sounds like a legitimate possible unintended consequence. Hat tip: Karl Woll.
