I had this discussion with one of my friends when we were driving on the motorway at a speed of 120 kph (75 ish mph).

I asked him to open the window and stick his hand out but first predict how much force he would need to hold it out. It was way more than he expected

That times 100 is how much force the car needs to overcome to maintain speed, I told him.
