I just realized my list excluded possibly my biggest pet peeve - dirty/greasy drivetrain. Not necessarily on others' bikes (not my problem if you want to deal with the mess).
I've ditched grease/oil altogether and have gone the Molten Speedwax route for several years now, and will never go back. Silky smooth and spotlessly clean.
I guess my years of commuting with a belt drive/IGH setup decreased my tolerance for dirty driveline beyond my already low level, once I re-integrated chains into my life.
