Unless you're strapping down loads manually, filling your tanks with an actual fuel bowser and recording your logbooks and handing them to your supervisor, you CANNOT dictate what others can do in a GAME! I get that it is Truck "Simulator" but it's not really. It's a simulation in the sense that you can drive trucks around city and countryside and deliver loads but that's where the similarities end. It's impossible to have an overweight load detected at the weight stations (illegal but it happens in RL), no random load inspections, no police RBT's, the list goes on.
You can't simply say "You can't do this because it's meant to be a simulator" when the GAME does not simulate ALL real-world scenarios. It is a GAME, not a true-to-life simulator. Some people just don't understand the difference.
