I agree with you that everyone should have enough sense to go past the minimium required safety gear - yes that is common sense, agreed.
But your remarks here plus later ones imply that you don't need rules to tell people what to do - this is why people with that mind set very sheldom grow their sports to a professional money making enterprise as in the UIM, NASCAR, CART or F1.
If you truely don't realize that many of the rules and safety protocol is there for protection of the sponsors and their brand image then you remain a "hobby" sport and not professional. Big corporate sponsors do not run to sports where death or injuries are acceptable again which you imply they are.
Even, in the NFL, they are constantly improving protective gear. Yes, people get hurt there every 10 minutes but there is a mitigation of the risk by having rules and safety gear and big sponsors want that, they demand that. The pro sports that have the best and biggest sponsors and rake in the BIG dollars are safe by design not because the particpants use "common sense".
I think you are missing that here and remarks/attitudes like yours are exactly what will get Joey's wife many millions of dollars, they were not "on their own", you paid money and signed a contract for a level of professional safety/resuce that they feel they did not get.
I apologize for singling you out and I believe you a good guy with good intentions and I know you're emotional about this as are many others but a lot of people in this sport have to do some soul searching and change the way things have been done to move forward.
ps I commend the extra efforts you take and maybe protocol such as yours needs to be adopted by everyone!
