I seem to remember a case of a HGV driver being found not guilty after running down a pedestrian on a crossing because he had stopped at the line and therefore the blind spot at the front obscured the crossing. It didn't appear to be thought that, if an HGV has a blind spot in front then stopping the lorry so they can see the crossing might be wise.
Blind spots on any vehicle are treated like a force of nature, a sad fact of life like freak weather accidents. We crowd into busy city streets and then allow huge machines which are operated half blind to mix it in as well. The design, size and visibility of lorries are not laws of nature, they are decisions made by designers, manufacturers and regulators. If the blind spot couldn't be used as a reason for "not seeing" someone and in fact was a cue to prosecute the operator for substandard equipment then I would imagine resolution would be found quite swiftly.
