Jet Setter Trophy
Compete in a race in every location.
Complete, not even win, a race in each of the 9 locations in the game. So one race in L.A., Utah, Baja, London, Croatia, Morocco, Malaysia, Japan and China. You will get this trophy if you are going for platinum, if not, this trophy can be done online - I know this because it popped after I completed a few races online before unlocking all the locations in Single Player.
