I think a useful thing for this thread would be a summary of things sims won't do autonomously, since this seems to be shorter. I only just found this thread, but have found it very interesting - it inspires me to make my own autonomous challenge, where you need to find the right starting household configuration and traits in order for the game to continue with the best possible outcome. You get 2 days at the very beginning to help them form useful habits, and then after that it's hands off except for important life events that they just won't do themselves. [edit: I think I'll have to allow 2 commands per day, but only items from the below list - my neat handy sim just won't repair the toilet, and so he refuses to use it and pees himself.]
Myself, I've never seen them leave the house autonomously except for work or school. As far as I know they won't complete opportunities on their own. I've never had sims woohoo on their own. They'll flirt nearly all day and be extremely irrestistable, but never actually go to bed, even if I've previously had them do so. They won't get a job on their own.
So to summarise what I've seen here so far, they wont:
- woohoo
- get a job/quit work
- leave the home lot except for work/school
- take photographs/still life paintings
- use the treadmill
- teach toddlers to talk/potty train
- answer the door
- complete opportunities
- move house/go on vacation
- pay bills
- have a party
- bathe the dog for fleas
- hunt
- reinforce pet behaviour
- call for services (fireman, police, maid, repairman etc)
- repair items (may be skill level dependent)
Useful traits for autonomous sims are probably:
- neat
- friendly
- flirty
- family oriented
- hopeless romantic
- handy
- brave (to deal with fires - can someone confirm that sims won't call the fireman themselves?)
There are probably more obvious things that need to be added to the list, so it would be great to have more suggestions. Perhaps something for the guide? I'm about to embark on this challenge idea, so I may be able to add a few more and confirm others.
One last thing: someone mentioned sims on high free will seem to be even more autonomous since Generations. I have noticed this too. It's frustrating how often sims I'm micro managing cancel their queues and go off and do their own thing while I'm not watching.
