IMO, it depends on how the design and layout are. There is a town about an hour and a half from where I live that redid one of it's main roads to add a cycling lane. Great on the surface, but horrible in how they did it. They have angled street parking. They put the cycling lane between the lane of traffic (for vehicles) and the parking spots. Everyone felt the cycling lane should have been between the parking spots and the sidewalk as it would have been less danegerous for the cyclists. (This is a beach city that has many inexperienced vacationers renting bikes).
