But the issue is that drivers of large vehicles are typically less aware of pedestrians. So how can I as a pedastrian be responsible for the situational awareness of the SUV driver? It kills me just as much if they are not aware of me.

I think other solutions would work just as well, just add sidewalks so roads become smaller, or make users of large SUVs pay for the cost of killing pedestrians.

>I live in an area where a high clearance SUV or other large vehicle is a necessity for navigating many of the roads. Why should I, and others like me, suffer for the externalities occurring in cities (this seems to pertain to) where I will never drive?

I don't know where you live but most SUVs are not really made for off-road use either and there are plenty of high clearance smaller cars around. Moreover, let's turn the question around, why should pedestrians pay (with their lives) so that some people in remote areas and many city people who want to feal like a outdoor cowboy can drive SUVs?
