Cities could create bus and bike lanes literally overnight. Load up a truck with concrete parking curbs and cones and drop them. No one is going to bike until the infrastructure makes it safe and convenient. Like safe enough to let a kid or 65 year old woman bike.

We just choose to continue subsidizing a triangle of car dependency. The government finances toll-free roads, mandates parking minimums, and enforces restrictive zoning. Businesses and real estate consumers pick up the tab on the real cost of free parking (higher rents and mortgages, parking garage construction costs). Drivers pour money into car loans, insurance, maintenance, and fuel.
