Poor advice, in my opinion. If one is trying to pan the camera/lens with a moving automobile, for example, the camera should be in one-shot mode. Forget the "machine-gun mode" completely.
Set the exposure mode to "M" (for Manual). Establish a proper exposure for the scene. Set the shutter speed according to the degree of background blur you want to see. For fast-moving race cars, 1/125 second should be a good starting point. The ISO and aperture can be manipulated for the rest of the exposure settings.
Focus on the spot on the track where you expect to make the image. Then, follow a car to the spot and trip the shutter at the right time to have the car in the right place on the track for the image.
This is really extremely simple. Just remember that you have to follow the car before and after the time that you trip the shutter. Smooth motion of the camera through the whole process is critical to keeping the car positioned properly in the viewfinder.
My advice was predicated on the premise that the OP had no experience shooting these types of shots. I recommended Tv OR Manual, which he could choose based on his ability. If the light is consistent on a track then manual would be my preference, but not knowing where he is shooting, Tv would be more appropriate when panning as the light can change quite a bit as the subject moves in and out of shadows. I would have recommended a specific SS but again I did not know what the OP's desired 'look' is based on his comments. Examining the EXIF of images similar to those he wish to emulate would get him close and he could tweak it from there.
There is nothing wrong with using short bursts, as I wasn't advocating 'machine gunning' despite my tongue in cheek remark about the FPS. I am definitely not an expert, nor do I play one on television, but I do occassionally shoot a moving target and have achieved excellent results using the method I described. However, it is NOT my field of photography that I shoot on a regular basis and would bow to greater knowledge such as yours. I understand the school of thought that rails against high FPS and spray and pray methods, but using multiple shots with constraint is a tool that can be used despite its stigma amongst some photographers. I am sure they don't make those 10FPS professional 1Ds bodies to shoot flower gardens.
