The roads are certainly built and maintained with capital diverted from more productive uses. Even if the postal service didn't lose money hand over fist I'd still call it subsidized, as it wouldn't exist without its legal monopoly.
One can argue whether road costs are covered by user fees or not. The subsidized policing and EMS costs are typically ignored, for example. You might want to include some of the military and intel budgets related to oil security.
