What does this have to do with chariots or am I missing some context?
The point you missed..... is that like chariot racing once was, the TT is a stupidly dangerous thing to do, yet it's a race many will willingly risk their lives to compete in for the challenge.
ergo, I'd much rather be a charioteer (a modern TT racer), than a comparatively safe gladiator (a modern boxer). :-)
Just supposing that being a chariot driver was more dangerous and lethal than being a Gladiator.
The Isle of Man motorcycle races (with a death toll of 1-2% per year) are, both today, and historically, one of the most dangerous motor vehicle events in the world.
IoM takes both novices and veterans. Yet, they all sign up anyway. It's a thrilling spectacle to be sure.
