Yeah, big oversight on my part. I should've explained that mechanic. I think I didn't because the gas mechanic was the second to last thing I added in the game, so the dialogue and text functions were already written and done at that point. I definitely should've went back and refined it in hindsight! Another thing I've seen is that people have had a hard time navigating the open world map effenciently. Since I designed the map, I innately knew where things were, so I was almost always able to take a perfect route - and I think I might've used those trials to determine the gas depletion rate. Another oversight on my part!
