Rush Rally Origins

Go to RXC gamemode, Time Trial, Peeler Cup. Drive a lap without hitting anything (or do multiple laps like I did, I did 5 laps), then choose Quit, after that achievement should pop. You don't have to get gold medal, I got achievement even though I only got silver medal. You probably can do this in any game mode but in RXC and Time Trial it's easier since there are no obstacles (fences etc.) or opponents that you might hit. Hope this helps.
