Let's jump on trucks yet again

[deesun]

Roads are built for all kinds of transport not just trucks. Do you think that if we took all the trucks off the highway between Sydney and Melbourne we would only need a single laned road? On a rail system if a train breaks down it holds up the ones behind it for hours. If there is a derailment it holds up everything behind it for days. For trucks it would be seconds and a few hours at most.
