To The Future Cars

Sometimes I wonder how cars would look like in the future, if it’s really possible that they can fly or float in the air just like in the movie “the fifth element”. Nowadays we have car gps inside our cars which tells us where to go, some even have voice commands. So I was thinking, is it really possible that soon, you just have to give voice commands to your car and they will be the one to take care of everything just like in the movie “I, Robot”? It may seem so great to experience them now but for sure it’s going to cost you too much as well.
