to return to the OP. Get a bell, ring it, lound and long, alert them to your presence. If that doesn't work face the awful, incomprehensible, reality that pedestrians have right of way over everyone else. (regardless of how they might behave when they are not pedestrians). and give way. What, apart from bugger all, does that cost? come weaving through the crowd at someone like me and you may find yourself off your bike and on the floor.
