Thoroughly enjoyed reading the above, especially the ww3 close encounter, which was skillfully avoided. Rockandrolldentist & co are obviously blessed/plagued with excellent hearing. My partner is similarly blessed(!!) she spends a lot of her time worrying about various inexplicable noises in her car, which I can't hear and neither can her garage! While I drive serenely along in my Dacia Duster in splendid peace and quiet and at home enjoy the super piano sounds of my px5s.
