This is the Thunder Mountain ride at Disneyland. Since I now have a camera that can do this, I played around with zooming the lens while exposing the image. This turned out to be trickier than I had supposed. You have to time everything just right; zoom the lens at the right speed; and make sure the subject is centered even though it's moving. I failed on that last one over and over. This was the closest I got.

What does it look like if you used an ND2000 filter and a tripod?
Save yourself some headaches. Just take a regular photo and do the rest in post.
