I love motion blur. I use it when the weather is poor, maybe heavy rain, nearly dark, and I have to shoot at a lower ASA to see anything. This of course requires long exposures, thus a lot of motion blur, often to the point of creating an abstract image. Often, I'll throw logic out the window and shoot blindly and fire the camera without checking the viewfinder or screen. The results can be surprisingly interesting, but I often get a lot of rejects with my legs reflected in the window, the side mirror cropped poorly, or an odd angle of the frame. This image is from driving around Lake Crescent in Olympic National Park, a few weeks ago.
