Have someone play Scania Truck sim or Eurotruck sim? When you bring trailer to destinations and you can park the trailer precise in parking spot for bonus points. Or you can skip it. Whell my suggestion is to make that in Garage to Garage Delivery for someone who is playing on wheel and wants more realism in the game. So when you drive the car to destination, you can chose to park the car precise on parking spot with pallets or boxes around the spot and you are trying not to hit them and you must use parking brake and shutdown the engine to finish it. Then when you are done with the delivery, you get bonus points for parking. If is not your type of thing, you can skip the parking bonus. What do you think about it? Is it possible to make something like this?
