The thing you dont see when the expert draws is he projects a framework on the page and knows the vanishing point, can see the 3d bounding box of the object, where parallel lines would extend from any point in the 2d field. When you start drawing, you practice by drawing these reference frames on the page. Eventually, you can just feel them like they are always there. This is why practice is important, its not something you can reason your way through. You need to program and train your brain like an animal. When its automatic, then you can try drawing the motorbike.
