I haven't yet read the draft, but I hope it starts along these lines:
Within three years Lambeth will be a place where anyone, whether a primary school child or a granny, able or doddery, resident or visitor, can thoroughly enjoy walking and cycling on our streets in a convivial way, absolutely without fear of being harassed of knocked over by the driver of a motor vehicle.
Within these three years those needing to use a motor vehicle in Lambeth will realise and accept their total responsibility not to frighten or bully (let alone injure or kill) those who wish to walk and cycle.
