Do you drive a car? Ride a bike in traffic? One false move and you are dead. You, like most people, are probably competent at these things that would be very risky but for your skill.
Each bad move on a solo is death. For driving, biking in traffic, it has to be a series of bad circumstances to mean death.
The soloists who achieve notoriety are either pushing the limits, or seeking adrenaline, which skews the stats, especially when you check the number of them that passed doing non-climbing activities. It's not particularly fair to compare that demographic to the average folks who bike in traffic every day.
Soloing well within your limits is like riding a bike on a quiet road, there are things that can go wrong, but something extraordinary has to happen for it to be serious.
Soloing close to (or outside of) your limits is like riding a bike on a busy motorway. The margins for error disappear and mistakes are far more likely to be fatal.
I've tried a few times but it seems entirely impossible.
One time I literally made it a months long project to learn to not leave my keys in the front door. To the point of programming my phone with random voice reminders and getting up to check at 3AM.... and I never got anywhere near 100%. I just use a lanyard.
I don't see how I'd ever drive when driving is made of dozens of tasks like that, and I can't even do one of them.
My list of rules and workarounds is long enough that I've actually posted them on GitHub and I treat counting to ten as a high failure risk project that demands care and triple checking.
