I remember all of that Alan, I was working in the building opposite the day it happened (30TSC). I also remember something falling off that same building some time later during its construction and going through the glass roof of the building below (the 'fingernail' as it was called), the tube station that was also under construction at the time (and I had just left the site about an hour beforehand). H&S is something that has to be drilled into people, there is always the misapprehension it will happen to someone else. H&S on London Underground was always first class from training to PPE to inspections and not being afraid to stop the job.
Back to the thread, Dom, Dave is right, it still won't be big enough, you'll just use it as an excuse to buy another bike!
