Just looking at gamergate sales and there is currently a LOAD of sims ranging from ship, heicopter, building, demolition, wood cutting, road works, bus, truck, train, plane and even Bungee jumping and automobile rescue.
Honestly certain things I can see being enjoyable, but refuse collection? Who would play such a thing? someone who does the job for a living and can't get enough of it? and they all seem so expensive most of the time too and look like they were made with Hammer.
