I don't think most cyclists blithely ride into the blind spot of a turning truck, though the accident data shows some do. OTOH it's easy to do when not intending to, or thinking about it as we filter up at intersections. You come to a line of vehicles stopped on a red, and as per usual see an opportunity to filter up on the right. The light changes and traffic begins to roll out, and oops there you are, caught in the wrong place at the wrong time.
