How many beverages come in glass bottles versus aluminum or plastic? Almost all beverages that people buy in glass are alcoholic. There's a bias there.
Moving to a 10 cent deposit REALLY cleaned things up in Michigan - I was a kid when they enacted it, and a group I was in did road cleanup as a community service. Before the deposit law, we would fill up more than two full size pickups with stake sides (extended sides so that the bed was now a cage 6 feet high) in our area, I think it was about 2 or 3 miles. EVERY YEAR.
The year after, we fit all the bottles in about 4 garbage bags. I'd guess that we went from 10,000 bottles and cans to maybe 300.
Almost all that I see on the side of the road is beer cans, from cheap beer. No doubt it's the open container law causing that - 10 cents isn't enough to make people risk getting caught with an open container.
