...and I'd agree with porridge (btw, I know llb was talking about motorcycling).
Personally, I think such posts serve a very real and useful purpose in reminding us all that it can happen to us. It is too easy to become complacent and whilst not overstating the risks, there are risks none-the-less.
Well for an inexperienced m/cycle rider (as with an inexperienced cyclist) maneuvering, they are every bit as vulnerable when alongside a HGV as a cyclist.
I guess the difference is that someone who has gone through their bike test will have received adequate training which allows them to see the dangers of such a maneuver, and most cyclists just get on and ride and any training they have received would have been through their car test which would not cover filtering or another vehicle appearing alongside them in their own lane due to the width of a car.
I think my motorcycle training and experience has helped me a lot when it comes to cycling whereas much of my car training is just not relevant by comparison.
