I had one the other day, terrible rain, pulling out of a junction to turn right and as I pull forward (there was a car in front of me and I was clear to pull out) a cyclist* comes hurtling from my left, ON THE PAVEMENT, with no lights.
It could have been quite nasty had I not been going slow!
* I use the term Cyclist in the loosest sense as I don’t consider these people as cyclists.
