And if he was swerving crazy like and out of control, you would be just like the woman and yell "Get out of my way" and barrel through?
Uh, no, if you read my earlier posts that's not what I would do. If I saw him swerving I would slow almost to a stop and also yell out "passing left" so that the kid and more importantly the adult could hear. If the kid cuts right in front of me with no warning, then there is an accident. A multi-use path is a risky place for anyone who can't stay in control. It's a public path.
