Mill Lane old Amersham on the corner of mill house .

This black metal post is not visible at night. The post is on a tight corner and there are proper legal lit black and white ones that should suffice in stopping cars going near the wall of the house. This post has been knocked down several times and then re set. I live at 7 mill Lane and when I drove home last night in the dark I turned the corner and to avoid a car coming round the corner scraped my car right down the side on this metal post! It’s set far to far into the road. Please can you either remove or explain why it’s in situ and if it’s legal ? I am planning on putting a claim in for the repairs on my car to who ever is responsible for placing such a dangerous post in this position.
