Anarchy: Rush Hour

The first opportunity to get this trophy to unlock is the "Tutorial" mission event, if you chose to play through it. If you chose to go for it in the "Tutorial", there you get to drive a car with all Level 5 Adrenalin Devices and unlimited Adrenalin.

There are 2 ways to perform a barrel roll. Both require you to have at least a Level 3 Front Brakes Device and Level 3 Air Control Device. You could gain a top speed, then "Jump" with an UP motion with SIXAXIS and immediately hold plus in direction of your choice or, by pressing on the D-pad after hitting traffic and immediately holding down plus in direction of your choice.

The first option is easy to use in the "Tutorial". The second option, by pressing is much easier to do in the beginning stages of the game when you have less powerful car.
