I ditched my car and have walked everywhere for the last 5 years, I must honestly say I'm glad they didn't take off. People riding bikes on pavements and people in their motorized chairs are annoying and dangerous enough.
I agree with you, but I think that is because we both tend to walk a lot. Fast moving vehicles (generally bicycles and skateboards) in foot traffic are a damn menace.
But I can see how in the vast empty sidewalks of some suburbs that riding bicycles on the sidewalk is a good idea, and did so myself when I was a child.
Um, no. You ever been hit by a bike? Then again I saw a car reverse blindly onto a main road and a guy on his bike go flying over it. I'm sure that hurt more.
Truth is there isn't enough space for sedgeways over here. Pavements too narrow, roads too littered with parked cars.
Sometimes governments actually get it right.
