Now come up with rules for how to treat the flipped vehicle. For game balance reasons, it must be a state the vee can escape by itself, and the penalties for being flipped must not be so severe that it can be considered mission-dead.
Barring outside help, I'm not seeing a way to make anything more advanced than Wile Coyote physics work for righting a flipped vehicle. Maybe something could be done with bridge layers, backhoes, winches, or salvage arms.
Any any liquid fulled ICE vehicle would have to be a mission kill because the fuel is now on the top of the tank and the fuel line would be at the bottom.
Flipping hovers could have a punishing modifier because the bottom would be too smooth go get a good grip.
Flipping a track could be be a bear to do. Until you get the all the weight on the back bumper, the tanker can reverse the tracks and pull away, maybe even pulling the mech into a face plant. If the mech tries to grab from the side.... Let me put it this way, if the mech tries to grab a spinning track, I could easily see a finger or two getting snapped off, along with a good chance of a motive crit.
Wheelies, however are pretty hosed. No way to right themselves, no plausible innate defense, just stop you grinnin' and drop your linen.
I suppose that any weapons could still work but the turret would be fixed in what ever direction it was in, and you wouldn't be able to spin the entire hull around on the turret, even if it balanced just perfect.
Based on Weirdo's guidelines, which I can't see a way to make this work without being unbalanced.
