Question about winds and cars?

Question

lets say your car is going north at aproximately 20 MPH. If the wind was also going north at 20 MPH and you stick your hand out the window, it would seem as if there was no wind right?

Answer 1

In the same line of thoughts:

- An aircraft may experience shear wind or microburst and go from cruise speed to stall speed thus shortly falling from the sky.

- Fast multihull sailboats can move faster than the wind because they add their own speed to the wind speed. The drawback then is that they can't sail much closer to the wind than abeam because their apparent wind is at a narrower angle.

- In an air balloon it is always calm. Old illustrations show balloons with waving flags; that can't happen in reality.

Answer 2

Correct, since you are moving right along with the wind.
