I also don't think they were too far off with the cityscape in the first one except for the aircraft so close to the skyscrapers. I guess they didn't take the noise and safety into account. They were also right about cars, trucks, and buses continuing to be around for a long time.

The one in the middle was futuristic for the time, but I think it looks antiquated now because of the cloverleaf. Although cloverleafs were popular in the past, their success depended upon courteous driving which is why they quickly fell out of favor. In other words, they fell victim to the "asshole effect." I know many older highways still have them, but I can't think of the last time I saw a cloverleaf incorporated into a new freeway and I do a fair amount of driving.
