I guy I knew personally - I used to row with him back in the '70s - was killed by doing precisely that at a junction. He rode up on the left of a large artic., the lorry turned left and his semi-trailer swung 'inwards' as they do, my friend was caught and dragged by the trailer along the road and, eventually, went under the rear wheels. Killed instantly.

The poor driver of the truck was completely unaware of him being there, the cyclist had been sitting in a blind-spot, and the driver was absolutely destroyed by what had happened. In cases like this one, it's not just the un-thinking cyclist who becomes a casualty - it's also the (completely innocent, in this case) driver of the vehicle, the first-responders, and witnesses whose lives are badly affected.
