If you are travelling at 70mph in a car, with a 70mph wind blowing in the same direction as you are travelling, does that mean that if you were to put your head out the window it would seem like a calm day with no wind?

Erm no, cause ( if I remember my physics lessons ) the air rushing past your window is being split by the force of the car and doesn't match the cars speed. Youd have to know the aerodynamic effects of the car at any speed to calculate the wind speed travelling past the window at 70mph. Then match that with a wind speed travelling the same direction as you and boom no wind.

Theoretically, if I were in open and flat terrain with no wind gusts and with
an exactly 70mph tail wind [exactly opposite of my direction of travel] and
I had an EXACTLY correct civilian airspeed indicator showing mph rather
than knots; THEN, with no other weather variations nor uneven heating and
in a vehicle correctly aerodynamically designed not to ruin any EXACTNESS-ES
then except for the debris [flying at different speeds in the air] that my face was running into -- it would seem like a bad day to have my head out the window as the inside of the enclosed vehicle would create a pressure
differential and mess up my hair and ashtray [or something similar].

It is a very hypothetical question the chances of a steady 70mph breeze blowing exactly the right direction and having a straight road all mean no matter how hard you try you will never find out in theory it works in reality it doesn't,

I dont really know, but I pose this to you...if you are driving at 70 mph, and a fly flies from the back of your car and lands on the dash... was he flying at 70 mph, or a measly half mile an hour?

Well, I'd suppose that you wouldn't feel much of a breeze. That is, until your car engine overheated because of no cooling air through the radiator.

No. Because even though it would seem so because you are traveling with wing you're car is still displacing the air in front.

yes, exactly.
you mean you've never done it before??? (not 70, but say, 20 or 30)
by the way, response to another answer.. humidity DECREASES air density... air is "lighter" the more water vapor it contains..

Depends on how dense the air is isnt' it? If it is humid, then you can really feel the pressure on you.

works for a balloon, why wouldn't it work for a car? riding in a balloon is like dead calm.

yeah, until a bug hits you in the eye.
