This is in response to the original post.
Nobody ever promised private space flight and flying cars, those were predictions. The main reason why we are not using space ships in place of cars is that they are really expensive. With our current technology, getting something into low Earth orbit costs about $10,000 per pound. Getting into space is not easy, it takes rockets which cost millions of dollars and can only be used once. If you happened to have $70,000,000 on hand then you can buy a seat on a Soyuz rocket and stay on the International Space Station for a while, so space flight is not off limits to civilians, although it's still not within the budget of the average person.
