Destroyed vehicles glitch
From Halopedia, the Halo wiki
First, you need a Spartan Laser. Then, approach near a vehicle (warthog preferably) and stand next to it (Means your body is touching the vehicle.) with the word Press RB to enter/ride/drive ........ on top. Next charge the Spartan Laser and just as you fired, enter the vehicle and voila!!!(Note: You can't drive or shoot).
