Also, if you consider the externalities of cars in general, there's the additional issue of designing our communities around them rather than around the people who live there.

This quote is kinda a meme by now but here's SimCity lead designer Stone Librande on how the team had to make parking lots unrealistically small for the game to be enjoyable [1]:

> When I started measuring out our local grocery store, which I don't think of as being that big, I was blown away by how much more space was parking lot rather than actual store. That was kind of a problem, because we were originally just going to model real cities, but we quickly realized there were way too many parking lots in the real world and that our game was going to be really boring if it was proportional in terms of parking lots.

If you spend any time looking at parking lots on satellite maps you quickly realize parking lots are nearly always at least twice as large as the building they are for.
