"each commuter cyclist is ONE less car on the road."

This is assuming a cyclist owns a car and would drive it if not commuting by bike. My assumption is that a commuter cyclist lives close enough to their work that they have other options to riding a bike or driving a car like walking. Also, clogged freeways are the congestion issue not clogged neighborhood streets. A commuter cyclist if he chose to drive would not typically be using the freeway as his driving distance is not great. To me it's a pie in the sky idea of utopia akin to taking away bathrooms and assuming people will pee less. Although I don't live in Seattle or even King County I get tired of my tax dollars being used against me. If Seattle were truly on their game they would encourage businesses to not locate downtown. Hypocrisy.
