The only map I know of where the vehicles get knocked across the map is MinusMegaArena. Just like seeing the trucks go flying, but all the Megas get tossed. Wouldn't this make a funny hilarious version of select maps to see the mino and other vehicles go flying when hit. They are not dead, but they are out-of-action until they land somewhere. That's why I immediately suicide if I can when sent flying. But most stay alive and waste valuable time hoping they land on top of building so they can snipe.
It's similar to the thrill/giggle I get when on StarReach, you nudge/push someone over the edge and they are still alive, and fall to their doom. Haha
