All great solutions, but the infrastructure just isn't there (as already mentioned).
Blame it in "brain-dead urban planning", or "stupid housing considerations", but that doesn't change the fact that biking to work is simply not possible for most people.
If you live in the suburbs of New York, biking to Manhattan to work just isn't practical. If you live in the middle of the country, biking to work can be a nightmare. If you live down South, again, very difficult. If you live in San Francisco, hope that your job is downhill.
Let's build a better infrastructure, and not accuse people of being inconsiderate or stupid.
