I'm wondering if it's possible to make gas stations in some of the maps to be functional. I got the idea from watching a few GTA V DOJ videos. If it is possible to do, I think it could work a bit like this; 1: Drive over to a gas station on the map you're currently in. 2: Park your car close to one of the gas pumps, doesn't matter which one. 3: Put your car in Neutral or Park if it's an automatic, and turn your car off 4: Fuel will be added to your car until you either A; turn you car back on, or B; completely fill up your tank. 5: Turn your car on, if you haven't already, and go back to driving. I have no idea if this is something that's very difficult to add, if at all possible, but I think it would be a cool addition/detail to add somewhere down the development line. Thanks for taking the time to read my idea!
There is a mod that adds a refueling feature: https://www.beamng.com/resources/added-fuel-stations-mp-compatible.12798/
