It would certainly be unique among car simulators. i mean you can set fuel levels in some racing games, so that you need to pit for a refuel, but i've never seen it implemented as a challenge.
There is a refuel station on ECU just put a car in a random place and set the fuel level of the car to a low level
I wish this will be similar to Gran Turismo. U should do a lap in a circuit without running out of fuel
What is the command to set the fuel levels in a car ? Like to start the scenario with half of the tank instead of it full
