Seems to work well! This shot shows a lot of movement, but the car itself is sharp which is what I like to see - something that's moving is sharp but there is a lot of blur.

This kind of photography takes practice. Examples can really help but I'm afraid I can't quite help with that yet (still getting used to the Mac switch). Sometimes I find that it's easier to keep both eyes open since on an SLR, the viewfinder is blocked out while the shutter is open - this way you can track movement. I can't see too well out of the other eye because the camera is blocking it, but it does seem to help a little. Experiment a lot, and you'll get there.
