i don't really like #3 or #4. both of those shots seem like the motion blur came accidentally, from an unsteady hand.
the out of focus shots on #1 and #2 are a little better. i think i would have tried to make the first shot a little more out of focus, and maybe crop out the bottom of the image.
i think i liked the second shot the best, but there's something about the photo that bothers me. i think it might either be the slight motion blur or the softness on the car interior.
it seems like you took the entire series while inside of the car, and you probably could have gotten much better shots if you took the shots outside.
