Exactly my thoughts. If I had a car park to pull into then maybe, but I kept moving, full lights on and hoped those around me saw me. Like you say, truckers are generally better on the roads than most but they probably feel a certain safety through size, height and weight; Justified mostly, but not always.
In the northern parts of the country they haul 4-6 full sized trailers: Cattle, ore, fuel, diesel, gas, pipes, mining stuff and sometimes grain. They do 140kph and don't stop for anything. They can be frightening for people not used to them, especially on a single lane (both ways) outback strip of bitumen. It's a matter of getting waybiff the road before they get there as they cannot stop or deviate. It's interesting times for sure.
re: 4-6 sized trailers
That's massive. The most I've seen at once is three, and that's plenty. I'd hope that accidents are infrequent, even if it's out in the middle of nowhere because the carnage and cleanup would be unbelievable.
They're monsters yeah! Accidents are pretty rare although when they happen it's often some tourist who has no clue what 180 tons of stuff going 140kph can do when a collision occurs. Reasonably rare though. Those drivers are very skilled.
