Take a look at this street scene from the recent Star Trek movie. It shows San Francisco in the year 2259.

Apparently in the universe of Star Trek, city streets will look pretty much the same 246 years in the future as they do today. Cars, a cable car, and a fancy articulated bus, all on a road with basically 20th Century lane markings. The pedestrian crossing and traffic signals are different, but it’s a wholly recognizable scene.

From Star Trek Into Darkness.

On the other hand, by the year 2372 things change quite a bit. These next 2 images are from the Star Trek: Voyager episode Non Sequitur, and show a street in San Francisco’s Mission District.

It’s a fully pedestrianized space, complete with a subway entrance to the fancy future Trans Francisco subway system. Very progressive overall.
