The accidents and near accidents I have witnessed in Los Angeles are people on wheels moving at ~10 MPH or higher against the flow of traffic on the shoulder or in a crosswalk. Dramatically faster than a walking pedestrian. People moving at these speeds on wheels also make unwise maneuvers to conserve momentum, unlike most joggers. As a third party observing several of these events, I noticed that the cyclist/scooter rider/skateboarder more often accelerates to attempt to make a stale light as well, quite the opposite of normal pedestrian patterns. This has only gotten worse in recent years, with many more people having motor-assisted wheeled contraptions and not a lot of common sense about their newfound speed.
