    I would love to have a set of pitot tubes so I can account for wind direction and speed on mpg.

    erm...I think pitot tubes would give you airspeed, but neither wind direction nor speed.

    Your need an anemometer and a weathervane, perhaps of an old guy with a scythe. Think I saw one of those sometime! :p

    A pitot array measures the air pressure and wind speed of each tube. A little math gives you the actual wind speed based on the differences in the measurements. Here are some details: Pitot tube - Wikipedia, the free encyclopedia

    Then if you hack into the nav you've got your ground speed vector, and can add to get absolute wind speed and direction....

    May I ask WHY you need wind direction/speed indicators? On a Prius?

    Just buy an old Cessna 172 and put blinkers on it.
