Safety has been working for for me for the last 30 or so years. Safety worked even in the days before the safety vest, seat belts in yards, pulling the key every time I exit the vehicle, blowing the horn when backing and 4 way flashers on all the time in the yard. Even with all these "improvements" to safety, I still know what's around me in the yard. Plus the eyes in the back of my head still do their job.
