I researched a smattering of these entertaining stories, and they are not urban legends, no matter how silly they sound.
For example, number 7 is real, even though it sounds fake. Here is the actual story:

Okay, so the inn’s owner (not a smuggler) had the license plate, not the actual smuggler. That makes it less dumb.
