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?
This will incentivize people to demand affordable transportation, transition to alternatives, get low income citizens a reason to not oppose increased cost of living. Big consumers have to pay, low consumers will pay a little but get more back.

Now that EVs are a thing, taxing carbon may not do what you expect.
