Are they 96 gallon toters? Those are at the perfect height to break fingers if you brush them. There's a nearby city that people put those out on on Fridays when I ride through. Luckily there's not much car traffic so they're easily avoidable. I've seen this issue raised in another commuter forum. I think that style of bin and truck is getting more common.
I don't believe so. I'm pretty sure they are the much smaller 20 or 32 gallon cans, like the one on the left in this image:
