The sidewalk makes a great freeway for some...If you look in the background, you'll see lots of crash helments. Those are connected to bodies on scooters riding on the sidewalk. To the right, on the street, are more scooters riding in the space between the car and the curb. Like rising water looking for a crack to open, the scooter operator will find a gap to squeeze in and pass through. Frankly, they're annoying. They believe they have the right of way with total disregard to the pedestrians on the sidewalk.
