Make sure that you UNCHECK enabled so it isn't active.
Now create a area trigger just past the finish line on the driving line.
Link it to a state event ON event.
link the state event to the curve data source.
So when your rider crosses the finish line he will hit the area trigger causing the state event to enable the curve data source therefore winding the exposure on the camera down to 0 over 10 seconds or whatever you set the duration at.
