Well I pass the refuse truck every week on my commute (did so this morning) - it's always got its orange flasher going and the men are always wearing hi-viz. And they've got a tough job to do, they're on a tight time-schedule, and their work, of necessity, involves crossing and re-crossing the road many times.
Honestly, seeing as I nearly always see the truck well in advance, I give them a bit of slack and drop my speed accordingly. What does it matter if I lose a few seconds?
And once, a few weeks ago, when I happened to come upon one of these trucks on a very narrow lane, barely wider than the truck itself, the driver saw me in his mirror and went out of his way to pull over to give me room to pass. A courtesy for which I have a lot of respect.
I think if you hit and injured a bin-man, you'd be on a poor defence.
Point?
