The worst I've come across is a jackass on an electric push-scooter. I was driving down a badly lit one way street, he was coming towards me at speed. He was in the centre of the road, was dressed in black on a black scooter with only a tiny reflective square just above the front-wheel. He avoided me a few seconds before he approached me, but I honestly would have hit him if he didn't. I only noticed his little reflective square moments before he appeared.
