The same just happened to me, pretty weird (I even have it recorded).
When clicking on "Driving Options", it's like you click "Exit" (menu and music fades out), except that it loads a new race: A one lap race on Silverstone without any drivers (the track doesn't load as well, trying to enter it leads to an endless loop).
Edit: Here's how to trigger the glitch:
Go to the Qualifying Time Trial, enter the "Online Rankings", go to either the Regional Ranking or the World Ranking and before the details load, go right and hit "X" (which would usually bring up the player details). Now the broken/template event should load up.
Edit 2: This should work on every event. When you do that in the first GT-R event, this (sometimes) doesn't bring you up to the template course, but straight to the Silverstone template event.
