Why do we need flying cars?

Everybody now days is saying that in a few years time we will have flying cars commercially available. And I just think why do we even need them? Why do we have small private jets for? Flying cars will just be an expensive smaller jet and nothing else. It will take a hell lot of lime to make them cheap enough for the common man to buy it.They still are not able to make the plane fare cheap enough, how are they going to make the machine cheap?
Then, what if you run out of fuel in mid air? There can be all hell of warnings and other things, but what if it did happened? And that there is no place you can 'land' you machine? then what? Oh, nothing.. just a few fools will have to leave this world. What's the loss.. right?

And then is the training. Not everyone can fly a plane. They have to undergo training. And that training is also quite expensive. Why would somebody first buy an expensive car and then spend more just to qualify to be able to drive it. That's insane.

What is the problem with the cars here on the ground? What if two cars collide with each other? You won't have a parachute on your back at all times do you? And even if you do have a parachute loaded up on your back, but what if you are unconscious. You still die. You won't be able to open the parachute will you?

Yes, people do die in car crashed down on the ground too. But just imagine, there are more ways to die up in the air (falling from the sky being one) than on the ground. So, it is obvious that flaying cars will bring more deaths.
Then is the problem of roads. I just can't imagine where the roads will come from up there? Why do we need roads up there you say?? Well, some idiot just fancied to drive (or rather, fly) drunk here and there are crashed his machine into a Boing 787. Doesn't sound good right?
 If there is no defined space, one is just going to point to his direction and start flying until the idiot collides with some other idiot.
Suppose you do have a space defined. One will have to be skilled enough to fly in that particular zone without crashing. And there are sky-scrappers being built everywhere. Flying one of the cars into these magnificent buildings is not a big thing. The target is really big you know...
I really don't see any merit in building cars that can fly. If they are still built, i think i will be the last one to buy them. Maybe some of the only ones sensible enough who won't even buy them.
Ill rather bye a bullock-cart or a 2 mile-per-gallon pollution machine that will do more than 250 miles an hour right here on the ground. Or, return plane tickets to Hawaii for a holiday. That will cover the 'feel of flying' bit too.
