It looks like the letter carrier has to reach down to get to that mailbox. Yes, they can reach it, but I wonder about ergonomics. Not all mailboxes are the same height, so you probably have to reach down for some, but if this is a representative mailbox, I worry.
The very first image in the article shows a driver putting mail in a mailbox. What more proof do you need?
