Welcome to the forum!
Interesting. First I need to ask some questions:
Below is a diagram.
I've assumed a LH drive vehicle even though I'm from the UK. Obviously we could 'flip it around' to RH drive if you prefer.
(1) Is this diagram roughly correct?
(2) So you look in mirror 1 and see things that are in position Y?
(3) Is this a puzzle which you have solved and are now posing for us, or are you still seeking an explanation?
(4) When you see something in mirror 1 that is actually at Y, is the image inverted or the right way round?
