Double Warthog driving glitch

Through a glitch in Halo PC one player can control or "slave" one Warthog without a driver to follow an occupied Warthog.

Walkthrough

This is a very intresting glitch. First you park two Warthogs, front end parallel to the back end, side by side. Then you sit into both seats LOTS of times which makes the computer think that you are in both Warthogs. Now here's the interesting part: move one Warthog and then the empty warthog will go to in the same direction. You can repeat the trick with other warthogs, scorpions, ghosts, even banshees and turrets. There was one video released that shows a person controlling five warthogs, the rocket turrets on the Warthogs, three ghosts, two scorpions, and two banshees, albeit, not very well. If you are in the driver's seat, simply pull the right trigger to fire off your weapons. Also note that this trick also works if you get out of the vehicle, i.e. you work two warthogs and then get out, the warthogs will move with you.
