When you are in a race, if you switch to Windows (ALT+TAB) all the
 cars in sight went crazy (yours too because it is not controlled). You
 can wait 4-5 seconds and switch back to the game. Now you can see all
 the cars IN SIGHT going mad (hit into the walls, go back, etc.). If
 you have problems pass to another phase, do that and everything will
 fix-up.
