Aircar wrote in another thread “And maybe start ANOTHER thread specifically for debunkers,naysayers and those wanting to indulge in putdowns ....” Since I do think the roadable aircraft is technical possible, but due to other constraints a development dead end I will start the thread. Part is that in some way I don’t like to put down a good argument about the technology due to regulatory, political, economical, the organisation of society or other “side issues”. So here we go, this is not about the technical solutions, but other implications of roadable aircraft. The mission and what you want from a roadable aircraft is of course part of this. Maybe by thinking about this the roadable aircraft do come closer. And remember, the one that consider serious discussions just serious and jokes just for fun have understood both poorly. (My bad translation from the original Danish text.) In the different threads concerning roadable aircraft at least these main topics have been mentioned against roadable aircraft: -Economics -Safety -Juridical -Infrastructure One example I used was about seaplanes. In part of the world a seaplane would work well as roadable aircraft. Then, why are they not used as such? Another consideration some people actually do like to live in towns, do that influence viability of raodable aircrafts?
