Cllr Cook (as far as I can work out) wants fewer streets to be 20mph, but for 20mph to be the speed limit wherever there is a "local need". I can only assume that, were he to get his way, the map of 20 mph streets in Edinburgh would look a lot like a Jackson Pollock painting.
He also attacks the current, "blanket", 20mph plan as being too "confusing".
I really cannot figure out how he holds these two views simultaneously.
