That's a huge catch! The Rover stats were the last thing I added and I never got to checking them, I'm also pretty sure it won't last long enough but I never did the math.
I was going for a moral dilemma, still solvable with creativity like dismantling the interior or tying a plant as a cart or riding on top. The survivors being an opposing force didn't come to me but that's also a potential angle if the players show no care for them.
Totally something to fix for the post-jam version.
