Ghetto wind tunnel
Some water condensation from the morning, a good wax job, and viola, ghetto wind tunnel.
Here you can see that there is a high pressure zone at the base of the windshield. All the rest of the condensation got blown off by the airstream attached to the hood. But then the airstream separates from the hood due to the high pressure zone at the base of the windshield; so the condensation is still there.
Another ghetto wind tunnel is driving behind semis in the rain. You get really good oil/grease streaks down the car.
