Dave W my wife has the same selective car noise filter. Maybe it only comes in the spouse model?
I can get into one of our two cars and instantly identify a funcky noise. The last one was a terrible high pitched metal shreaking sound when ever you went over the slightest bump. She had been driving that car for weeks and never noticed it. I was stumped for about three days, when one day I finally figured it was coming from the passenger front wheel well. It was a valence sheet metal panel, that was hanging by it's last rivet, near the front shock absorber, when I found it. After the truck was fixed, she said, "hmm I never heard anything!"
Now if I was to mutter some snide comment say, in the garage, and she was within 50 feet, she'd nail me for it
