You have to be joking. I "have to put these figures into context" Cyclist only make up a fraction of the total commutors coming into London each day and how many of these travelling by train are killed each year or have life changing accidents?
My only "excuse" for stopping cycling was that I'm scared of death. The cost of rail travel is easy to take when you consider the potential for serious injury or lung desease.
Very few will say they're not scared of death. But take into account that you'll have cut the amount of exercise done by yourself and the effect of doing so.
There's workarounds for nearly everything these days. We can cut the risks, but can't exclude them. Crossing the road, on a crossing earlier this week, I'd a driving instructor tell his pupil to go through the red light, just missing me.
We can hide, but it'll find us. Keep pushing those pedals.
