These are really interesting traditions!
The only things remotely similar I can recall in my own culture are:
- it used to be the norm for men to walk on the road side of the sidewalk relative to women, I believe to protect women’s clothes from being spattered with mud, though, not attacks 😂 
- there are people who choose to sit at a table such that they always see the door, so that if a threat enters, they can act quickly
