I am a Senior who still rides his bike on city streets. I contend that it can be a dangerous situation when trying to share the road with cars. I have become increasingly frustrated by the changes and so-called improvements of bike lanes in Hamilton. Reducing car lanes has obviously increased congestion and frustration for cars and their drivers. They fall short of providing bike riders any degree of comfort and safety.
Here is my idea: Why not save a ton of money by simply paving a two-foot bike lane beside a sidewalk? It's cheaper and most important safer for bikers. Streets are for cars; bikes belong off the roads.
I do not feel safe when sharing the road with traffic. I can't tell you how many near-collisions I have had with distracted, speeding or just plain angry car drivers. That's why I have no problem driving on sidewalks. When I encounter pedestrians, I go out of my way to apologize for being on the sidewalk and many agree that riding the road is a dangerous thing.
Hamilton has wasted millions of dollars in redesigning its roads to accommodate bikes but I believe from first-hand experience that it's not working. I would rather share space with pedestrians and leave the streets to the cars.
Such a simple idea; why hasn't anyone thought of this before?
