For this to unlock I suggest going into multiplayer and then selecting "Jam Session". Under the filter make sure that "Impact Ratings" are turned on, this is the most important step. When creating a game, this is found in the Advanced Settings. Now either find a game or host a game, and your objective is to race very cleanly. Make sure to not hit anyone, and stay away from damaging your car. If you complete between 2-5 races completely clean, you will unlock this achievement.
Keep in mind this achievement can be boosted with a friend and you can both do a short 1 lap rallycross race while slowly completing the track together to make this easier.
As an extra bonus, after a few races, your "green circle" emblem should change into a "white hexagon", signifying the Honorable Driver status. You will now receive a 20% bonus on fans after every race.
