As others have told you, you are wrong.
US highways do pay for themselves (<https://web.archive.org/web/20130515013017/http://www.rita.d...>) (non-PDF version: <https://web.archive.org/web/20170712175437/http://www.rita.d...>), and help pay for other modes of transportation. Transit receives the biggest subsidy per passenger-mile, with rail and airlines in between.
