Mitchell - to add to what Glen said above... sometimes a thread will "take on a life of its own" and go completely off topic. You are new on here ....So, don't read anything into it if this topic goes that way... It is not a sign of disrespect - unless the people posting begin posting disrespectful, flippant remarks....
The best advice I think you got so far is to contact someone in charge.... and do give Nathan's concept of a hovercraft roadster some good natured consideration.... it could bring new meaning to the concept of a dual purpose vehicle!.... racecar and aircraft.... and Nathan, I think, is an engineer...so... he probably knows something that we don't...
