> This is particularly a problem when people are leaving buildings onto sidewalks unaware of cross traffic moving at 10+ kph. Bicycles belong on the road with other vehicles.

I can never understand how anyone can make this argument without seeing how it applies even harder to why bicycles shouldn't be on the road with cars going 45+ MPH (~70+ km/h).

Bicycles are closer to pedestrians than cars outside of the slowest city roads.
