I think a pretty big percentage of US container trucking is railhead-destination rather than long distance source->destination. It feels like a lot of freight is transported by truck when you are on the freeway, but if you go to Europe or India (where rail is mainly passengers) you'll find the roads comparatively choked with trucks. I'd love to see some numbers though -- this is all surmise.
