Getting some blur in your pictures is going to be a combination of changing your shutter speed and the camera pan mode. For shutter speed, the longer it is open (longest is 1/60th sec), the more of a blur you will get. The shorter it is open (slowest in game is 1/8000th sec), the sharper and more still your image will be. Try taking a picture at 1/8000 and then again at 1/60 and you'll see the difference. The pan mode in the camera options will also come into play. One mode makes the camera move with the car differently, so the car will be sharper while the background is blurred, one is the other way around, and I don't know what the third is, lol.
