Do you stick your head out of the car window?
Just like a dog, only without your tongue hanging out of your mouth.
I personally do it all of the time. I absolutely love the feeling of the wind crashing onto my face. Feels like sitting on the front seat of a roller coaster only it's only as scary as sitting in a car is. It's especially great when the driver picks up the speed and gets to 80mph or so.
It's just that I feel like i'm alone on this one.
And for those of you that haven't tried it, you have to give it a go xD
