Maybe for the occupants, but for everyone else they seem strictly worse, not to mention the visibility much be much much worse, making it a somwhat iffy tradeoff.

There are no crumple zones in a truck really.. You have straight frame rails. I guess the cast iron engine block gets a little crumply if you hit it hard enough..
