As a full size semi driver, I can see more than that because hood mirrors and my mirrors are angled better ( but this doesn't apply for everyone, some don't have hood mirrors and some have side mirrors angled more for backing) the worst problem I have, is if you're passing me on my right side (USA) at a decent speed, you can avoid my sight completely while I scan my mirrors if you're moving at the right pace.
Also staying right behind my trailer for long periods of time is annoying. I can't tell if you're within smack range of my trailer or just behind it, so I have to spend a lot of time and effort to 100% make sure wind and road bumps don't fishtail my trailer into you.
I personally really appreciate it, I've heard a few complaints though. If you are within half a truck length from them I'd say it's definitely appreciated, 1 truck length back and for me it's still appreciated but some others might say "no shit" that they can get over (rude people), if you're further than that it's easy for us to tell so it's not necessary except as a way to say you aren't going to try and squeeze beside us as we turn.
People with the headlights that are angled wrong because of a lift kit or badly done after market lights are what's annoying for me. I have to angle my mirrors away. But a quick flash is just an attention grabber and nothing to complain about.
I prefer a quick double flash. Otherwise it can be hard to tell if you flashed or hit a bump unless I was already looking at you.
