And Crumb asks "what next?.." Well we have had 30 years of development since this was drawn, and I think the 13th panel of the above intersection would show larger cars and maybe some vacant stores. And the shame of it is that a few miles further out of town, they may still be on panel #10 or 11, headed down the same path.
A year after publishing the above series, Crumb added the following three scenarios:
In reality, we have gotten a bit of all three of these final panels. Some cities (or parts of cities) look more like the Disaster panel, and after the disinvestment and abandonment, the final two are often tried as solutions. I would equate the Futurama panel to grand Urban Renewal plans in which everything is demolished and new modern buildings are built. The Ecotopia is closer to a Hippie version of the New Urbanist model, with all the walking and biking, though much more rural. I was thinking that someone should draw a more realistic and optimistic new panel. What would it look like?
