Rather ironic as what that video so clearly and educationally demonstrates is how more experienced cyclists handled the same situation.

Taking the lane and controlling the flow of traffic around you is an effective strategy for the bold.

Staying out of a singular traffic lane except to use it to pass an obstruction on a shoulder or parking lane after checking that it is clear is an effective strategy for the timid.

Just doing your own thing and ignoring everyone else may be legal, but it is not effective for survival.

When it's your own life on the line, be the one who makes the decision about what is or isn't enough space to safely pass, don't delegate that to others.
