No worries, we all get justifiably frustrated and angry sometimes!
"I would say though that drivers who are willing to get into big wagons that aren't fitted (or have been retrofitted) with up-to-date mirrors of at least the minimum standard of that council truck, ultimately should be bearing the blame if they then drive over someone who would have been clearly visible in said mirrors. For instance, it's legal for me to take off my left wing mirror as I have a rear-view in the estate, but I would argue that if I killed someone who was blatantly "there to be seen" in the left wing mirror, I've got nobody else to blame."
Hmm substitute Operator for Driver and I might agree, although never having had the extra mirror is not the same as removing one already fitted. The problem is the driver is in no real position to do that. As long as the wagon is legal, the transport managers answer to "I demand you upgrade the mirrors" is likely to be "**** off down the job centre and sign on then, the other drivers don't have a problem with them". The driver is, after all just an employee (exempt owner operators).
For example at my own work, I could push up the system "the mirrors on truck type X are imo inadequate, they should be upgraded to new wagon standards in the interests of safety". I'd stake a lot of money the answer would involve some or all of the lines;
"these trucks are legal,
there is no history of accidents caused by the existing mirror fit,
there are far worse wagons on the road,
they are in their last quarter of life so not in line for upgrade" and ultimately, "we have 1000* trucks in the fleet, we are not about to spend £150* upgrading each wagon at a cost of £150,000 plus the cost of down time while the wagons are off the road plus the cost of workshop time for an unproven upgrade which is not legally required".
Whilst that is undoubtedly cr*p for anyone who may be unfortunate enough to be maimed or killed, that's the logic :-(
*figures are wild guess based on vague memory! Certainly conservative as the glass on a main truck mirror will cost you over £50 on its own!
