well i found out just recently if you drive a warthog (or any other UNSC vehicle) through a 10x10 gravity volume it will start going up in the air like a ramp i experimented with it for a while and i made a small racetrack using this feature to go up a floor of the building that i made for it (it was offline though) it is surprisingly very funny and it would be a good feature in halo 5’s forge if 343 notices this post.
