Exactly. The bike lane network plan in LA county has been on the books for 10 years now and its still a patchwork mess in the second largest city in this country where you could realistically bike to work every day of the year. There is no hope elsewhere for change. If you don't already have it you won't ever have it or you will be beating sand until you die fighting for a mile of bike lane or a single train line that waits at red lights.
That kind of proves my point though doesn't it? There is a definite demand for bike lanes. However, civic participation is abysmal for everyone but the elderly who tend to be NIMBYs. If more people pitched in, we wouldn't have to rely the efforts of a few hyper-dedicated individuals.
