Basically blames cyclists for getting left-hooked by a lorry which *appears* to be overtaking the cyclist and then immediately turning left without slowing (it's hard to tell with the jumpy editing).
Actually they've got one thing right - if a lorry does do that to you, you've got about as much chance of avoiding it as you do avoiding a piano falling from the sky.
