Anarchy: Rush Hour

To get this trophy you will need to hit objects that a count will display in the "Race End" statistics under the category "Knocking Objects" on the bottom.

V.V.C. - blue porta-potty's near freeway and around the park.

Stadium DM - barrels.

The Rechnoy Vokzal DM - lamp posts.

Liberty Island - park benches in center of map.

Tropics - wooden boxes and construction barriers, all over the island.

Grinding this trophy is by far easiest on either Liberty Island or Tropics but, use the above information while going through the Story to shorten the time for unlocking it. After the Story, set up a "Best lap time" race in "Quick Race" from main menu with the maximum amount of time available on Tropics and grind away.
