Wind has a huge effect. Most people cannot even feel a five MPH wind. But, at 60 MPH, that is the difference between 55 MPH and 65 MPH airspeed depending whether it's a tailwind or a headwind. The difference in aerodynamic drag is proportional to the square of the airspeed, or 40%.

Reminded me of several of my crosscountry trips from CA to texas when I would be on the high plains on hwy 40.
Once I could literally feel the car being pushed along!!!!!
Another time the cross winds had all the cb anteneas leaning at 45degree angles!!!
