I’m curious how much (assuming US), slams happen on the left, middle, or right of a path.

Pattern I’ve generally seen is:

• Those not following vehicle traffic conventions (those on the left) give way to those following traffic coventions (those walking on the right).
• If both are walking in the center, both shift to traffic convention.
• Exception is made for those that are motionally restricted (carrying a lot, wrangling children, old, handicapped, etc.)
• Those unencumbered and moving faster are expected to weave.
• Always avoid bicycles.

Both as a man and as a woman (I’m trans), I haven’t had a problem following these rules.

That said, I’m 5’11".

It might be a height thing, not a gender thing or convention thing.
