When you see down in a car it is fast and when you see up it is slow?
this is because you are very close to the ground, but far away from whatever you see when you look up. Because of this, the angle of your neck will change quickly to stay looking at one spot on the ground, but because the sky is far away, the angle of your neck will not change as rapidly. It's hard to explain in more detail.
