Or, how the auto industry made pedestrians unwelcome by a focused marketing campaign to change consumers’ perceptions about driving, streets, etc.

I’m not interested in demonizing the auto industry here, but rather I’d like to suggest that how our community has been built or will be built in the future is not just market demand, but government regulation and funding, as well as private sector promotion to steer the market.  If that’s right and we’d like to see some change in streets and walkability, then what are the policy pieces which need to change?  It’s not just requiring sidewalks or bike lanes, but considering the broader context of how our choices have been constrained and what we need to do to make different choices easier (and more affordable).
