Presumably it has actually flown at least once in a test flight, under a specific licence for that flight. Otherwise yes, it's vapourware.
So yes, the company does show a few videos of flight tests, even though they are not licensed to sell it to be flown by customers.
Of course, the real struggle is to find enough customers at this high price point. Since customers will still need to drive to the airport and clear a flight plan with ATC when they want to fly, the situations where this drive/fly combination is useful are not widespread.
