We have a nice trail here along the lake for bikers and walkers. However, I would say about 50% of bikers ride on the busy 4 lane road next to the trail. A couple years ago a biker on the road was hit by a car and injured. There was uproar on the local Facebook groups, etc. about the biker being on the road when there is a separate and protected trail specifically for bikers 20 feet away. The biker crowd said they preferred the road to avoid the walkers on the trail. Point is, you can't win. As someone who cycles on a road bike, regularly at 15-20 MPH who's feet are clipped into pedals, I will always prefer a road to a busy "multi-use" path. Between people walking 4-wide, uncontrolled kids, and leashed dogs running from side to side across the path smelling everything, it's almost impossible to bike down a multi-use path at any reasonable pace without risk of injuring myself or others. When I was in Amsterdam bikes, peds and dogs all used much smaller sidewalks and it all seemed to flow pretty well. But bikes also all had bells on them and peds would move to one side when they heard them. Even tourists picked up on this pretty quickly. I often felt bikes should be mandated to have bells on them if they want to use sidewalks because you just can't hear them coming up on you. It's hard to get out of the way for someone when you don't know they're there.
