You are not the first one who ask me about the wheels blur, so I decided ot make short tutorial how to do it in Photoshop CS3. First I thought to send it to you by PM, but I think it will be good to post it here, cause may be it will be in use of someone else. Works only for side views!
1st - load the image in photoshop CS3.
