Our world has a small amount of people with actual flying cars. The flying cars that we have today are called Aerocars. These are not actually "flying cars", they are just cars attached to plane parts, parts similar to those of Aero Planes. Aerocars can hit the market from costs going up to 3.5 million. When you watch sci-fi movies, or play futuristic games, you see cars, no wings or plane parts, just a car with rockets that can defy gravity at a fast rate. The cars that we think about having in the future aren't realistic and it's close to impossible to create actual flying cars. The chance of us living in mars is greater than us having actual flying cars, without a 10-foot wingspan.
In today's world, we have various sets of technology. People live in a world with A.I. and even the power to fly to Mars, but we still don't have flying cars; at least not the flying cars we're expecting.
