EDIT: Changed to a “feature suggestion” based on Joko’s response:
Filling up the tank costs $57 when I am at 46% fuel, meaning $57 would give me 54% of a fuel tank. This works out to be $1.05 for each percentage point of fuel.
The Jerry Can costs $30. Logically, since that is about half of the cost to fill my tank, it seems a Jerry Can, it would fill half of the missing 54%, which is 27%.
Instead, it only filled my car to 57%, which was only an 11% increase. That makes it seem like I paid $18 for the can, and only got about $11.61 worth of fuel from the Jerry Can.
Then cost me $45 to fill it the rest of the way at the pump which logically tracks with the previous math, so I don’t think any bug happened, I just think the issue is that the Jerry Can doesn’t give enough fuel percentage for its price point.
