Its got to be the laminar flow over and around the windscreen. there is an area of low pressure formed behind the wind screen as it travels through the air. This will suck every thing around it in. What we must remember all the dirt and moisture that makes a car dirty in daily use gets sucked in. This also lands on us in an open car. WE ALL CALL IT FRESH AIR.
