Technically, you also have the compression of the wheels -- when the wheel turns, part of the tire in the front gets compressed while the back gets uncompressed. This is also a friction loss. Plus there is some friction between the rubber and the road. But my point is that the amount of

The plane gets pushed either forward or backwards by the wind, depending on the wind direction. The prop seems to only get turned in the direction of normal rotation, even in a tailwind, which seems wrong to me. But really the main issue for me is that this amount of wind should not move the
