Will, you should have a switch at the front of the camera to switch to MF (manual focus) you focus on the object or piece of track which is on the racing line, then switch to manual focus. As the car comes towards the point you focused it will get more and more in foucs, until it get to the point were you set the focus. This is called pre-focusing, and is what everyone did before the joys of auto focus.
