This unposed photo by your travel4seniors.com editor illustrates how the no scooters on sidewalk sign is ignored by thoughtless riders of the grown-up kiddie toys. While adult and child walkers are trying to avoid racing scooters, they may stumble over a stack of abandoned ones spread across the sidewalk waiting for new reckless riders.

City scooters are supposed to be limited to 15 mph on the street, but single racers and mindless groups of them go much faster illegally on sidewalks. So, in your city travels, if you’re an elderly and physically challenged hiker, be alert for speeding scooters racing illegally on sidewalks and busy street intersections.
