Flying cars? We are going to need a lot of infrastructure in place (designated roadways, flying markers, traffic control and signage, driver safety, mass pilot certification, etc) before we ever see flying cars become a widespread thing. I don’t see that happening this century. Oh, and I don’t think the airlines are going to sit still for any of that 😉

Not to mention the number of people who would actually be qualified to navigate a flying car year after year would always be small and therefore would not justify the expense. Not to mention insurance costs, liability, etc. The only way I can see to do it would be to have it all automated somehow, which would raise all sorts of other issues.
