Frank, what's up with you and yaw, yaw, yaw? If you are traveling down the highway at 70, and you have say a 5mph crosswind at 45 degrees, the resulting yaw vector is so small as to be negligible.

If you have hurricane force winds at exactly 90 degrees to the road, yaw might be a concern, but most of the time around here, any breeze is so slow that you can barely feel it.

Just look at all the tuft testing pics posted on this forum. Generally the tufts are pointed straight back.
