This would be incredibly frustrating to me as a car driver. I don’t think having shared roads for a vocal minority of bikers makes sense. It basically slows down everyone to bike speed, which I realize is the unspoken strategy of bike activists, and it is also why I am against supporting bike-friendly policies in their current form.
