This is all cool until they roll over and kill someone. A guy that works for me was doing asphalt a few years back and watched a coworker break his neck with a bobcat (nicknamed "kill dozer"). He was backing the machine off the trailer, looking out the side and somehow the bucket dropped while his head was hanging out the side of the machine (no safety guard). My buddy was standing 30 ft away wondering WTF is this guy doing just sitting there (not seeing what just occurred). He was stunned for weeks that the coworker died doing something so simple/ been done thousands of times/ not screwing around.
