Don't get me started...there's always someone (many someones, usually) arguing that cities shouldn't spend money on more bike lanes, when the auto traffic is so bad and there should be more car lanes. The cost of bike lanes is a rounding error compared to auto lanes; literally, foregoing adding a couple miles of additional highway lanes would pay for a whole small city to get bike lanes crisscrossing it, and could support more people.
And, I definitely attribute my good health (well into middle age) at least partially to biking so much throughout my life. Getting a few percent more people out of cars and onto bikes would help save the world in all sorts of ways, IMHO.
