I live in Perth in Western Australia and "road trains" are kept out of the city. Truck routes are a constant subject of public complaint/debate. Trucks and buses here do carry warnings as I mentioned. Everyone knows they are a hazard. So do you, why do you say no one acknowledges it? The higher class of license requirement acknowledges the extra danger. Most drivers have never run over anyone and I can't see how a feeling of invulnerability would lead one to run over a pedestrian. You are right about one thing - very many traffic problems stem from poor attitudes and inattention rather than from "driver training" or the type of vehicle, but this thread is about the relative safety of certain vehicles in particular situations. Around schools that often means when they are not even being driven. If we were talking about driving around the bush, the arguments would be reversed.
