Which is a valid reason, as the data clearly shows the benefits of growing up in neighborhoods with high income earners, and the disadvantages of growing up in neighborhoods with low income earners:
Of course being in a wealthy area is better than being in a poor area. But does the existence of such areas benefit society? What would it look like if more neighborhoods were mixed income and public resources were shared equitably?
An imbalance will cause discord and disorder. Hopefully you catch yourself on the right side of it. Prioritizing cars is very much a “me and my immediate family” above all else move, and that can be an easy choice when you don’t see others as belonging to your tribe, or vice versa.
Roads are still necessary for delivery, garbage disposal, emergency services (fire engine, ambulances, police cars) and construction equipment. The picture is extreme to the point that it fails to deliver it's message.
Fewer cars means fewer lanes are needed. I’ve seen intersections 9 or 10 lanes wide in US cities. How can any senior citizen walk across 9 lanes of traffic, especially at night. One or two lanes is sufficient for all infrastructure like waste removal or emergency services.
But the root of the problem is insufficiently dense living. People have to make a choice to sacrifice their expansive living quarters (such as in Tokyo, Hong Kong, Manhattan, London, etc), otherwise the whole public transit and de-prioritizing motor vehicles doesn’t work.
As I explained in other comments, obviously people do want their space. But is that a luxury they can afford? They’re future generations can afford in terms of infrastructure debt repayments and environmental damage? Health damage from over reliance on cars? I guess we’ll see...but I’m betting not.
