A fair bit of litter I see (on roadtrips at least) is from overflowing bins at rest areas where the council is using poorly designed bins, people are over-stuffing them, animals are pulling things out looking for scraps, etc. The small amount of local litter appears to come from rubbish trucks tipping bins into the trucks on windy days.
