From what I'm told, your hair would still whip around as if it were in a windstorm, but why?
PLEASE ASSUME THE CAR IS A CONVERTABLE! (sheesh, people. Come on!)

Cool question! I had to argue with myself about air displacement by the moving vehicle and the tail wind, until I realized that there was also a wind in front of the car as well. Once I determined that there would indeed be a wind in front of the car as well as behind it, the answer became clear: No wind in the car.
;-D Your gas mileage would be terrific as well!

If you are going around in a 55mph steady (that is very important: no wind gust has to be assumed) wind, and the wind blows on your back, you are therefore staying in the same pocket of air, and your hair should be still (mine definitely would be, but that is because I am bald).
Now, there is something else that needs to be looked at. The wind cannot be 55mph all the way to the ground, because of friction, it has to slow down the nearer to the ground you are. As your car is travelling at 55mph in a pocket of air that has different speeds, it is going to disrupt that profile. That will create turbulences, and that may cause you hair to move a little bit. But not like your were in a windstorm. That would be the effect of a 55mph real wind, which varies as a function of time (gusts) and as a function of whatever obstacles on or near the road might redirect it slightly.

Close the windows. Regardless of the wind outside, now you are travelling at 55 mph with a little bubble of wind also travelling at exactly the same speed. And no, with the windows closed, your hair doesn't whip around...unless you have the fan going really hard.

The hair would have moved even if there hadn't been any wind. It is simple. It is called inertia.
Hang something from the roof of your vehicle and hit the gas. You will notice that the object moves in the reverse direction of your vehicle. The point where it stops moving is the point where the acceleration force of your car, the gravitational force applied to the object and the tention force of what you have tied the object to the roof with are balanced.

I don't believe so, if you're traveling at the exact same speed as the wind. Ever run forward into uncomfortable wind? Turn around and run in the opposite direction, and suddenly the wind stops. Halt your running and there's that cold nip at your neck again.

Theoretically, no. But, of course, there are cross-winds that the car makes. So, yeah, your hair will whip around a whole lot.

Moving of hair when by car at the speed of 55 kmph dosen't
depend upon the direction u r travelling i.e.it dosen't depend on
what u r travelling in the direction of windor opposite to it.

If your car is moving at the same speed as the air around it, then no, your hair will not move around.

55mph x 2? Car's speed + wind's speed

of course your hair will move...
underlying air current flows thru the car creating a lift for your hair to fly all over the place !
