Even without Peak Oil and Global Heating roads will never compete with rail. A few days ago a French TGV broke the world record for a conventional train when it reached 575kph (357mph). These days cars have a job maintaining a tenth of that speed!
The high speed network is spreading throughout Europe and will still be there when the last cars and aeroplanes splutter their last in an oil-free future. And if the power supply is sustainable - using hydro, sun or wind power - they'll still be running ten thousand years into the future.
