I've never fallen because I failed to unclip (and never will)
I don't patch old tubes after a flat. They sit in my office for about a year until they are cluttering up the place and I throw them away.
I do a few centuries every year. I'll occasionally let a group draft behind me for awhile and then intentionally hammer over a roller. If they can stay with me I'll slow down and chat with them
I built my last 2 CF bikes without a torque wrench.
