A theory about cul-de-sacs

I know this new theory isn't even remotely true, but I'd like to posit that cul-de-sacs exist for the benefit of people in aeroplanes.

Cul-de-sacs look fantastic from the air. They add lovely twists and turns to a city. They are, however, significantly less good for people on the ground. They take up loads of space, they're quite confusing, and they cause getting places to be more time consuming.

This leads me to believe that cul-de-sacs exist to be looked at from the God's eye view, which is to say, the aerial view. Pre machine assisted flight, the only people/things/animals/fictional characters who got to look at things from above were birds and God(s). These days, sixty dollars gets you from point A to point B in an hour, with the added advantage of a killer aerial view for the duration. The result is that everyone can have the view from on high.

We're all gods now.
