arent harnesses supposed to be at like a certain angle pertaining the body
this is so that in case of rollover, since a rollcage would not be present your body and head is able to move in a certain way in to which your head would not be crushed
that is why you are supposed to mount the harness to a mounting bar, and not mount them like at a 45 degree angle or to the where the rear passenger seat area is?

ill do some research but i know its something along those lines
