Do you think banning bikes would be easier/less costly to enforce/better for your community than making it safer for cyclists to share the road with cars (which is usually why cyclists ride on sidewalks in a given area)? If a ban was established on bikes, but not cars, to parts of your city where people need to go, and cyclists continued to go to the places they needed to go… what would enforcement of that ban look like? Pulling them off their bikes?
