Don't get me wrong though. I think they can, and should, get a concept demonstrator built. Let's just be realistic and not pretend what it isn't - a personal vehicle people will use to go around town.
By the way, the installed HP required to hover (for a flying 4-seat car) is going to be -eeee-norrr-mous. Like, nearly a thousand horse power enormous.
Also, I dont think NASA is being dishonest, but they are definitely hyping it up for the public to get money for this thing. Given NASAs budget can you blame them? Ehh.... I dont know. Dr. Moller has been saying his flying car will work for the last 30 years, yet still no car. Be weary of anything VTOL.
