Reduce funding for car-friendly infrastructure
There are two sides to encouraging more people to leave their cars at home (or not buy one in the first place): 1) make alternative modes of transportation cheap and efficient 2) make driving more inconvenient and costly. I suggest that the city of Vancouver set a goal of progressively decreasing the percentage of the budget set aside for expanding and maintaining roadways for automobiles. The money that is saved should go directly towards affordable housing near the city center, better transit, and more bike paths. Once more people have switched to alternative modes of transit, existing roadways could be reclaimed as green space/gardens.
