Just a warning if you are driving in our neck of the woods. The new average speed camera system has been installed over the last day or two and is being tested on a long, straight stretch of the A9 (direction Lausanne - Martigny only). The first camera is placed near the exit for Aigle and the second is just before the exit for Bex.
They are big, mean machines, quite unlike anything I've seen before and guaranteed to stir fear into the hearts of the unsuspecting.
