The example, from an Airbus A380, combines a pitot tube (right) with a static port and an angle-of-attack vane (left). Air-flow is right to left.

I've been thinking that the drip rail down the front of the doors on a VW bus is well within the frontal area. A serrated Gurney flap there would be exposed on the leeward side and could have a similar effect if it were sized appropriately — maybe 1/2" to 1 1/2" serrations? Worth a Photoshop?
