I have been southbound from Maitland on the F3 in A six axle rig grossing 44 tonnes in teeming rain and mist, visibility mostly 100 metres and less. I was tucked in between another 22 wheeler and a B-double and all three poking along at 80 k's. There was a continuous stream of little wheels passing at speeds of easily 120 or more, boring into a grey curtain in which there could be anything hiding out of sight, just waiting to be run into.
