Hello everyone. Can you tell me what means menu COMPETITION in the game? When you go to "Single player -> Features -> Competition. Here you can type some access code (look at the screeen i upload). Is anyone knows what that access code do? What this all about? Thank you for answers!

Apparently this was a feature to share codes for magazine/website competitions, as in who sends in the best time to win some price. The code entered sets stuff like game mode, player car, course, etc.
You can generate a random code with the cheat code cactaceae (entered in the competition menu without code entry selected, followed by enter). I don't know how specific codes were generated, probably with a tool only the devs had.
