We don’t get snow like this where I live now, but we did in the northeast U.S.A. where I grew up. This meme (below) shows thoughtfulness for the mail man!
With these curbside mailboxes, the mail man drives and can put the mail in the box from his driver’s seat. Where I live now (southeast), this type of mailbox – at the curb/street – is very common, even in town, in residential neighborhoods with many houses. Where I grew up, this type of mailbox you saw mostly in rural areas. In town, the mailboxes were attached to your house – either on the front porch or your front door had a mail slot – and thus the mail man walked from house to house carrying a bag of mail.
* P.S. I suppose calling this person the “mail man” is outdated, but it is still what comes to mind. Other options would be: mail carrier, postal carrier, mail woman, mail man, etc.
When I visited Finland, I got to see a mail woman that delivered the mail via bicycle. See here.
