Is Back to the Future Part II  still a sci-fi movie or is it a piece of historical fiction? We certainly don’t have a lot of the technologies it promised us – most namely flying cars.

But, strangely, a future of flavored coffee options, streaming TV, electronic cigarettes, and K-pop music hasn’t satisfied our longing for personalized flying vehicles. And what better place to vent our collective frustrations than social media?

What would you gladly trade for a flying car?
