to you people talking about the speedway endurance race: try this.
1. get the escudo with max horsepower
2. widen the gears all the way
3. put it on auto transmission
4. start the race
5. tape the x button down
6. tape the joystick a little bit to the right.
7. come back in an hour.
The only probem with this is thast sometimes you get stuck by the pit stop, or go in the pit stop multiple times. but if everything goes as planned, you will win by at least ten laps
