For PS plus edition users, forget about getting this in tour event. Select single event and race. Choose any track from Tamil Nadu and get a car of your choice. The tracks are wide open and you have 90% of chance to avoid hitting or be hit by other racers. The trophy requires only that you don't hit other racers. Hitting the track barriers or going offroad is perfectly fine. That is how i got this trophy
PS : I am from Tamil Nadu :D
