I'm just wondering how they're going to ensure that someone landing in a neighborhood isn't going to land on a car or a person. Air taxis are probably an eventual reality, but I'm curious to see if they could really get this thing approved by the FAA in the next three years. You're talking about a whole new set of regulations and safety rules. Unless they put something like a heliport in the middle of a neighborhood, kind of like a park n ride lot where everyone could drive to it. I guess that'd still be better than driving to the airport. It'll be interesting to see how they pull it off of it ever gets that far.
