How close are we to flying cars?

Could flying cars be the answer to avoiding bumper-to-bumper traffic? Inventors have been trying for decades to create flying cars, though it seems the idea of self-driving cars may soon be closer to science reality. You're stuck on the highway. A commute that should have taken a few minutes has now somehow become an hour-long endeavor. When this happens, we all have one of two thoughts… One, Monster truck… Or two, I wish I could just fly over this mess.
