Further to the email in Saturday 7th January Telegraph Motoring, I have a plastic clip on the right hand side of my 9-year-old Citroen C5 that I use to hold parking tickets. When I got the car I asked the salesman what it was for, he said that in French law a form had to be displayed on the windscreen and the clip was to hold it, also that as the windscreen was the made the same for right and left hand drive cars though designed for left hand drive the clip would hold the form on the near side on French cars and not obscure the drivers vision but on cars for the English market would be on the drivers side. He did not say what the clip should be used for in England.
