Make it compulsory for all bicycles to have a warning Bell or Horn.
Why is this important?
So that cyclists can alert pedestrians that someone on a bike is approaching them from behind. Pedestrians have no way of knowing that they are being overtaken until the cyclist is upon them, then it’s too late.A simple ‘ring ring’ would make almost 100% aware that someone is approaching them.Then they would step to one side and allow the impatient biker to pass.
It must be made compulsory.
