Vertigo: mirrors & mirror images

Scottie returns to Ernie's after Madeleine's death
Introduction of Madeleine at Ernie's Restaurant
The flower shop
 Madeleine: It's as though I were walking down a long corridor that once was mirrored, and fragments of that mirror still hang there. . . .
Scottie: The small scenes, the fragments of the mirror. . . . Do you remember those?
First visit to Judy's hotel room
Judy: "You have got it bad, haven't you?
. . .She's dead, isn't she?"
Judy decides not to run away
Looking for the gray dress
Waiting for the made-over Madeleine
Scottie: It shoud be back and pinned from your neck--I told her that, I told you that. . . .
Judy: We tried it, it just didn't seem to suit me.
Scottie: Please, Judy. . . .
After the consummation, Scottie's discovery, seen in the mirror
The necklace in Scottie's insanity dream
Is Scottie driving on the wrong side of the road, or is it Madeleine's point of view in mirror image? (Or perhaps the British Hitchcock, who claimed not to drive, forgot that Americans drive on the right side?)

Driving back to the Mission
His earlier insanity dream, though in mirror image (plus he doesn't fall)
