Regarding Cllr Scott Arthur's 2k "against" emails:
Don't forget his ward lies to the South of the affected area, but not in it. So most of the complainants will be people wanting to drive through someone else's neighbourhood rather than using the main road.
I spoke to a resident of Cluny Dr the other day, who was very much in favour of the filters, and reckoned most of her street was too. They pointed out that a lot of school children walk to school along Cluny Dr, and it has suffered from rat-running.
