Realistic Weigh Station Frequency

This small realism tweak for American Truck Simulator changes how often you get pulled into weigh stations. Compliant carriers with a clean record will now bypass more often, just like the real-world PrePass and Drivewyze systems. You will still get pulled in occasionally, but nowhere near as often as the default game behavior. Perfect for fleet management players and anyone who wants a smoother, more believable highway experience on the long roads of ATS.
