I had a fairly detailed response from Ellie Reeves about this. She pointed the issue out to the police and local authority. I’ve attached the letter from Lewisham, who say they’ll look at some more yellow lines on the road. The police said they’d step up speed checks on the road and offered to take me out with the speed gun. Text pasted below.
I am writing to you following your recent complaint into motorists speeding on Devonshire Road, SE23. Although I have not witnessed any speeding motorists on this road myself, I do appreciate the fact that I nor my colleagues are able to patrol this road on a 24 hour basis and these incidents, unfortunately do occur, which is evident from your recent complaint.
In response to this, I am more than happy to come and speak with you in person and discuss with you what our, as a police team, intend to do to hopefully deter motorists from acting in this anti-social manner. I will touch on this briefly in this response which is to conduct a number of vehicle initiatives on Devonshire Road making use of our laser speed detection camera. Also with regards to this, and another reason for wishing to meet you in person is that I would like to know whether you would like to accompany us on one of these initiatives, if anything to see how we address these particular issues and deal with motorists found exceeding the speed limit.
If you would like to meet with me and/or accompany us on such an initiative, then just let me know when you are available for me to come and discuss this further with you. I am on duty over this coming weekend and am available between the hours of 3PM and 8PM on Friday 07/09/18 and the same for Saturday.
I hope you find this response satisfactory and I look forward to hearing from you in due course.
