With my hand against my car door while driving, i noticed no airflow pushing my hand, but only when my hand was against the door panel. Could be the air is passing over the back of my hand with little disturbance at 50 - 60 kmh, i 'll try higher speeds when i need to use the highway.

Once the form is good having a polished smooth surface would benefit the cd, no ?
