Very very sad indeed.
I rode to work today, and I feel a bit nervous cycling in London at the moment, but also reassured that I light myself up light a christmas tree to make sure I'm seen.
On my journey today, going through forest hill in South East London at about 7am, it was still dark and a bit foggy, a cyclist coming towards me was dressed in black, a black helmet, with no front light and a very dim led light on the back attached to his rucksack that either needs recharging or new batteries (or throwing away). He was completely unoticable. I felt quite worried for him.
