I believe a substantially larger percentage of commuters would choose to not bike (or walk, take transit, etc.) if they had a choice — meaning if we designed our world around people rather than cars. We can still have that environment if we choose to, and we have to start somewhere.
For what it’s worth, I recently completed a small survey for a college class in which I asked commuters of various ages what their ideal commuting method would be, and nearly half of the respondents selected an option other than the car. I think there’s substantial pent-up demand for alternative transportation options in our region; it just has to be made readily available and useful for people to take advantage of it.
