A kid a few years older than me from my days playing baseball was heavily injured at around 16-17ish by a tow strap. Word is he was pulling a friend out of a rut, the strap broke and went in through his rear window and hit him right in the face. I believe he broke his jaw and had a skull fracture.
It's enough that when I have used tow straps, winches and such....I keep my head down as best as I can.
To reduce those danger you can use a winch cable damper or improvise with a heavy blanket or coat.
Also be aware, with traction plate, they can be thrown back by the wheels...
