Hi,I have a set of Milenco mirrors which comprise a flat one (UK offside) anda convex one (UK nearside. The convex one is great for UK use as in most cases it is viewing vehicles that are slower moving so I can pull over to the left, or watching vehicles joining the MWay dwon the slip roads. Howver I am going to France and am a bit woried that the convex mirror may not be so good for watching fast moving traffic ona motorway so that I can judge my opportunity to pull out and overtake slower vehicles. Any views please?
