I'm all for continuing to improve the cycling infrastructure, but seriously doubt it will ever have a serious impact motor vehicle use outside urban centers. How people live will need to change before they change how they move about.
Most people who use a bicycle for transportation do it because its their only choice, are cycling enthusiasts, or as part of their personal beliefs.
For me, road suitability and distance aren't an issue, its terrain, long steep hills beyond my abilities and desire to deal with after a days work.
