The demographics regarding participation are well known to be self-fulfilling negative prophecies. That is, if you don't build the infrastructure, then participation declines (or stays low), and particularly amongst the groups you mentioned. Low participation from a particular group != low latent demand. I've ridden in every Australian state capital bar Darwin, and rate Sydney drivers as the most aggressively incompetent of the lot - which, combined with the spectacular hostility of the state government to cycling, is a clear recipe for low participation. Notwithstanding which, I agree that mass transit infrastructure should be built up to the level where it is an easy choice for every commuter, and not the unhappy choice for those within reach of a station.
