Having any car or truck is a choice. People lived before the automobile. They do provide benefits, just as SUVs and trucks provide benefits. The Amish live without cars, so too could we if we chose to. In fact, the Amish could make the same claim about all automobiles that you make about preventable deaths attributed to larger vehicles.
Is your point that taller trucks and SUVs provide considerable benefits over shorter ones? What are those benefits?
Or do you mean simply that trucks and SUVs, regardless of their height, provide benefits? I don't doubt that and do not mean to imply otherwise.
