Don't let this one scare you in any way. It is ridiculously easy to get.
Go into the game's settings and set the handling to Elite. Now choose Quick race and a short track like the Hazyview Oval. Set the number of opponent drivers to 0 and laps to 1. Rest of the settings don't matter.
As soon as the "race" begins just complete the lap and that's it.
Trophy is yours.
