for you to say something like "bumpers aren't a safety issue" pretty much discredits you immediately, but i'll answer anyway, for posterity.
"actual bumpers" are quite likely the single most extensively regulated pedestrian- and collision-related safety part. there's extensive legislation about their design and characteristics.
car companies exist to make money, yes, but they operate within a global framework of strict regulation.
Feel free to look for an actual regulation that prevents ridged bumpers with shock absorbers. You will not find it and in fact many vehicles are sold that can have a 5MPH collision without significant harm.
The reasons for this is people can walk into solid objects at 5MPH without significant harm.
