Ban motor traffic from Truro city centre at the weekends!

I would like to see Truros Piazza lose the bus route across the centre, only then can it really be a friendly place where parents dont need to hang on to children for fear of being squashed by buses. Also why not pedestrianise Boscawen and River streets on the weekends? No need for cars and trucks to creep through this beautiful city. Just think how peaceful, safe and cleaner the centre might be for people to wander carefree.
