My original question was “How do we disincentivize the purchase of pickup trucks/SUVs” but then I thought it would be better to approach the larger problem of car dependency and car ownership. One option is, of course, to create public transit infrastructure and improve it where it already exist. This, however, doesn’t change the fact that some will still choose to drive. What would be the best ways to discourage people from owning personal cars?
Basically this. Make it so that people live in places conducive to not owning a car. If people live places where it is miles between their needs and there is no accessible form of alternative transport, you’re stuck with cars.
