Sims walk to most irrational trashcans:

I prefer to make bigger more filled houses (they look more realistic) because of this there are trashcans in multiple locations to help with throwing out dust. Additionally, for sims that like to repair things, they need more trash cans than the average sim. Having more trashcans would be helpful IF the sim actually walked to the nearest trashcan instead of heading upstairs, across a lot or outside to one that wasn't even remotely close. Time is crucial in sims sometimes and taking 45 minutes to throw away a piece of trash kinda sucks when it could've taken a couple seconds (sim minutes) and a 180degree turn.

I'm not sure what is used to determine what trashcan they go to (other than outside vs. inside) but perhaps changing it to most convenient/closest available would work better.
