I sent a copy of an incident directly to a local force (elderly lady driving straight towards me on the wrong side of the road with her windows fully steamed up, causing me to swerve left). I was informed that a traffic officer would be on his way to speak with her and the following month, her car was up for sale and I got a call to say that she had given up driving! I felt quite bad about her losing her independence but better that than someone losing a loved one. (We had our two year old grandson in the back of the car with us) She made no apology to me when I eventually caught up with her and stopped her. I managed to find the demister for her and she had no idea where most of the controls were or what they did!
