Not to mention the design of those lids is intended to keep the dumpster closed so water won’t collect and animals won’t get in. They’re kind of heavy, so the wind won’t open them. They’re also designed so at that angle, with that wide a swing, it’s not easy to get those lids up at all, almost impossible to open it all the way and leave it open.

That’s why they’re usually built with side windows. They don’t generally want those top lids to open until the truck comes.
