This is exactly how it is in the rock climbing community. People still die, including very experienced people. You only need to mess up a rappel weight transfer once, but you have to execute it successfully thousands of times over the course of your life. People cope by saying they're careful and it's the irresponsible people who die. It isn't true. No reasonable safety system can rely on you acting perfectly every time. A low-probability-lethal-failure activity that you many many times can get you eventually, no matter how careful you are.

I don't say all this to disparage GA, or rock climbing. I rock climb and intend to do so well into the future. But saying these sorts of things mean you aren't treating your hobby with the seriousness it deserves imo. It could happen to you; thinking otherwise is self-deception.
