I find it kind of sad that all the sci-fi writers back in the 70's envisioned flying cars (a la Blade Runner) by this point in our history. Instead, we're stuck with an over glorified moped.

They started writing about that back in the 20's and 30's (read Hugo Gernsback's stuff -- just don't look for literature). To date nobody has licked the air traffic control problem.
