Question of wind and speed

If there was wind blowing at 50mph, and I was in a car traveling and that same speed, in the same direction, and I stuck my hand out the window, would the air be still? (Assuming there is no variation in wind speed and vehicle speed.)  

hmm...dunno...why don't you try it and let us know how it was...  

In theory, yes.  In practice, no.

You see, when we do physics experiments and wind tunnel testing (even then), the wind is always perfect.  It flows in a straight line and doesnt bother anything.

In real life, any wind has to overcome turbulence-causing obstacles: other vehicles, the ground, obstacles on the side of the road, overpasses, etc.  These obstacles cause the wind to shift, move and basically become turbulent.

Also, the car you're in creates its own set of turbulence and has to cut through the air (even if you and the wind are going at the same speed).  In any case where something forces its way through, you'll feel it.  

You also have to take into account actual direction.  Wind doesnt follow one precise direction at 50mph, like your car does.  It goes off to the left, then to the right, then up, then down.  Its never perfect.

So if you stick your hand out the window, you'll still feel the air, just not as strong as if the wind were stagnant or in another direction.  

Oh, huh, I never thought about the wind shifting. So then it's impossible. Yeah, heh, I was planning on trying it one day, I won't anymore.
