This is another achievement which requires that you go to multiplayer career mode. You need to earn the following badges:
50 online races: This can take a while. You do not need to win the races. You just need to finish 50 online races.
Start Last/Finish 1st: If you find yourself starting at the back of the grid at the start, play to win. Alternatively, you can get your mates to wait while you win the race in order to get this.
3-event win streak: This can be challenging if you’re up against some good players. To avoid getting annoyed, playing with friends would be the best option. Ask them to wait whilst you win 3 races in a row.
Clean race: Play it very safe. Do not hit anything. Do not ruin your kudos bonus by clipping the side of a wall. Do not power slide. Just race, slowly. You may lose but you will earn this badge. It can be quite hard as people might try to make you swerve so again, do this with friends.
Win each scenario: Now this will take a while. Complete every online career event. This can be done easily with a few friends but is time consuming. Just play as you would if you were playing single player career mode.
