autonomous laundry

I am playing an ISBI challenge and can confirm that sims do laundry autonomously. Take it out of the basket, into the washer and out of the washer into the dryer, the whole process. I have four household members that I do not control and two of them do laundry autonomously and neither have the neat trait. The two who don't do laundry have the lazy or slob trait, so that makes sense. Unfortunately I had to lock the laundry room because cleaning the lint trap is not an autonomous action and they keep setting themselves and the room on fire. Constantly guarding the dryer is not my idea of a challenge.
At the end of the day I don't really mind as I was never planning to use laundry in any other household, but this has to be a nuisance to all the laundry enthusiasts.
