Deadly Momentum

 "Get eliminated in a race on Novice difficulty."

This trophy is very easy to unlock, and as the description says, requires you to be destroyed on track in a race on Novice difficulty.

If you find that you have not obtained this trophy naturally, then simple load a race on the correct difficulty, and grind your vehicle into the wall of the track continuously, until you are at critical energy. At this point move to the center of the track, and wait to be destroyed by your opponents as they make their next pass.

The trophy's class is Bronze.
