Often in doing a road rage event, you'll end up at critical damage. Just pause the game, view the map (hit the "back" button) and see if you're near a repair shop. In progressing through the game, eventually you'll end up in critical damage and be near a repair shop.
However, if you want to get this achievement quickly, use the road rage event nearest the original garage.
To the southeast is a repair shop, maybe 2-3 blocks away.
Simply start the event, drive slowly or turn around/sideways, and alow yourself to be wrecked until reaching critical damage. This usually is about 2-4 wreckages. Assuming you stayed in that area, once in critical damage just go through the repair drive-thru and you'll get the achievement.
