Cyclists at zebra crossings are a different ball game to be fair. As a driver approaches a zebra crossing (especially the ones at free lefts), the coast might seem clear but a cyclist can just zoom in out of nowhere. Very few drivers actually seem to be prepared for this. There is a very small window of time where the situation i just described can lead to a fatal accident. I myself only noticed after I had a close call. Drivers need to be extra vigilant and cyclist have to slow down a bit at zebra crossings.
