In the UK the law is sufficiently vague. https://www.legislation.gov.uk/uksi/1997/2400/part/I/crossheading/movement-of-traffic-at-crossings/made https://www.legislation.gov.uk/uksi/1997/2400/part/I/crosshe... “ Precedence of pedestrians over vehicles at Zebra crossings 25.—(1) Every pedestrian, if he is on the carriageway within the limits of a Zebra crossing, which is not for the time being controlled by a constable in uniform or traffic warden, before any part of a vehicle has entered those limits, shall have precedence within those limits over that vehicle and the driver of the vehicle shall accord such precedence to any such pedestrian. “ The point is that simply waiting to cross you are not “on the carriageway” and therefore the driver of the vehicle is not required to stop (by some reading of the law). Common custom is that you do stop for people waiting to cross but sometimes you really do have to stick a foot into the road to make people stop for you and allow you to cross.
