Cars and planes have different basic designs. When you try to merge the two you end up with a vehicle that does nothing very well.
Still, it would be intensely cool.

Also, there is no flying cars in the public streets, but there are everywhere in tech sites, and videos. When will they actually make it for all of us, instead of being greedy?

Well, I dont think we have flying cars for 2 reasons:
A) technology has not been developed to that point- yet
Now even a baby could fly them.
There are now fully-featured flying car prototypes flying, propelled by gas-turbine engines, same engines used in helicopters...

A turbine can meet this weight requirement; however, a small 100 HP turbo-shaft can cost $100,000, while a single 1000 HP turbo-shaft can cost $300,000. The smaller turbo-shaft gives a poor specific fuel consumption, while the single engine provides no back up. Any design using turbo-fan engines will expect even higher engine costs. A turbo-fan using disc loading like the Harrier generates only one half pound of lift for every horsepower. Hence, the Harrier requires approximately 40,000 HP with little payload capability in the VTOL mode. To meet the 2 HP/lb requirement in a small fuel-efficient form, only two engine alternatives appear to be possible at an economical cost:
• A turbo-charged or super-charged fuel injected 2-cycle engine. This engine would need to be developed.
• A rotary engine that employs aluminum housings, peripheral porting and an air-cooled rotor. Engines of this design are in existence.
