Even so, I think many possible discoveries haven't been invented/revealed because of financial interests in the world. Which is sad.
Flying cars are a different story... I heard there was one manufacturer that could make them for ~$30k, but the gov wouldn't let them build it
I don't really want flying cars anyway... people cant drive, and i don't want them flying into my house... navigation would have to be fully automated, and require regular maintenance so they don't fall out of the sky, etc... flying cars are more trouble than they are worth
I'm waiting for the flying speeders. No more losing traction in tight corners.
