Both of those stories quoted above were in the online version of the mag only. As far as waiting until the Elio starts rolling off the line, Pop Mech ran its first story on the flying car in the April 1906 edition. As far as I know no practical flying cars have rolled off any production lines in the intervening 120 years. The flying car in the April 2016 edition will cost $200,000. I don't think that that will change much of anything and certainly will not be a big game changer.
I'm going to respectfully disagree. A [practical, reliable, and autonomous] flying car will be such a game changer that anytime a flying car prototype or even concept comes out of the woodwork, these mags will invariably cover it.
Not so with the Elio; the bar for coverage is quite a bit higher. As much as we all like the Elio, it is not a flying car. It will be a game changer only when it begins to get mass produced and indicators are such that it will remain in mass production at high levels. When that happens, it crosses over into game changing territory, and the auto mags (both conventional and online versions) will cover it. They'll have no other choice if for no other reason than it's got to be a more exciting story than the next iteration of the Corolla or Civic.
