Regarding the smoke haze, does some of this not have something to do with air pressure, especially in colder climes? I seem to recall as a young fella being educated on the smoke running sideways out of household chimneys in Stanthorpe, mid winter, with not one bit of breeze about.....and that of the small "smog" that seemed to be over certain parts of Toowoomba's hollows in the 70's on account (largely) because of those old Kero heaters?
On the matter of the lengthy idling, whilst I have no set opinion on the topic, I do understand that large bus fleets often found that keeping an engine warm (through use) did seem to extend engine life, and limit the amount of operational issues whilst in service. These same vehicles once passed into private ownership, usually found themselves on am and pm scholl run work, shut down over weekends and shut down more than running - and then the bugs start creeping in.
Just a thought or two
