Lessened visibility is due completely to rollover protection regulations. Vehicles around the 2010's+ require stronger A,B,C...pillars etc. Automakers complied with the regulations by making pillers both larger and shorter. Shorter members are stronger as there is less bending moment. If you look at where the windows start on newer vehicles they are munch higher. Thus body lines to match this brings up the hood.

This is astoundingly obvious when you park an unmodified 80's-90's vehicle next to something new.

The question to me is what overall reduces mortality rates, improved roll-over and side impact protection or driver visibility?

Personally I think blind spots everywhere suck and would much prefer better visibility.
