Us cyclists see all the broken parts of cars as we cycle along. The rarely swept gutters have all sorts of bolts, rubber grommets and other pieces that have fallen off cars. I had wondered where these pieces of spring I find had come from. Is this photo part of the broken suspension springs you have mentioned in your column? The unusual thing about this particular one is that it seems so new. It's still got most of its shiny black paint on, most are rusty when I find them. Only a small piece seems to have broken off - won't the rest just expand to fill the space? Incidentally it was found in a road with seven road humps.
