Apologies for not updating. Whilst I personally found it interesting there wasn't anything earth shattering.
I don't know what the safety rails are but I could kind of guess from context.
More interesting, for me, was the first section on the haulage company that was investigating sensors and camera etc. They seemed to be taking the issue seriously. The sensors down the side of the truck seemed of particular practicality to me; basically, they detect movement down the left hand side of the truck and alert both the cyclist/pedestrian and the driver.
The haulage fed president (or whatever he was) was the model of diplomacy and wasn't going to be drawn into contentious areas. He gave a very reasoned and measured interview, as one would expect, and very much ran the 'shared responsibility' line.
All in all, worth a listen but nothing to get stirred up about.
