No, it would not be a good idea to make Stillness Road one way. Perhaps those car drivers should brush up on the highway code. The road does not have any one way signs. Just because it is no entry at one end does not make it one way. That together with the fact that there are white lines down the middle of the road, that the humps have white triangles on the left side, etc. And yes I have seen cars lawfully do a three point turn to go back towards Codrington Hill.
