Because you normally place a mirror vertically. If you put a mirror on the floor, it reverses up and down just fine.

They don't reverse anything. They reflect (reflections of normal mirrors will always appear to have left and right reversed, because when you line up with a reflection the light going into the mirror must come out of the same place).

a mirror reverses left to right but not vertically because it's the reflective property -- it does not perform like a recorded image, that displays what it sees as anyone else may see it, it reflects what is directly in front of it, leaving the right-left to be reversed because it is not an independant object facing you, it is simply a copied image reflecting. It not being an independant object, the logic of your right being someone facing you's left doesnt apply, leaving anything in the reflected image to be "backwards" . And some mirrors do reflect vertically because of a concave axis.

A mirror doesn't reverse left and right. It reverses front and back. Think of it this way: Take a Sharpie marking pen, and draw a picture on a transparent sheet of plastic. Then look at your picture from the back side of the sheet. That's the same image you would see if you viewed the front of the picture in a mirror.

Tequila will make it reverse up and down too. Everybody knows that.
Actually, a flat mirror only reflects the light that falls on it.
If it becomes unflat, it can focus light at different places.. If it becomes unflat and concave enough, it will focus light and flip the "image" at a certain point which will appear to be inverse.
Your brain is confused by this inverse image effect. What is neat is that if you lived with this inverse world long enough, at some time your brain would acclimate itself to that world and it would seem natural. Your brain would then be confused in the non-inverted world you "came" from, just like when you drink too much tequila.

The way I see it, the image from an object in front of the mirror goes in a straight line from the object in front of it, and then sends it back out in a straight line, so it only appears to be reversed. Is that about right?

It reverses 'back to front', not left to right, nor up and down.
Stand in front of a mirror and hold your right hand out to the right, with the thumb upwards.
The image has the thumb upwards too - not reversed up/down.
The image has the arm to the left of the hand - not reversed left/right.
Someone standing behind you sees the image with its PALM closest to them, but your actual hand has its BACK nearest to them - it is reversed back/front. It has the effect of turning RIGHT into LEFT, like turning over a cardboard letter R.

Depends on which mirror you're looking at and the angle from the perspective which reflect the view. The point is that mirror is a reflection based on the object stand point.

It's because your eyes are separated left-to-right. If you rotate your head 90 degrees and look in a mirror, you will find that up and down are reversed but left and right are not (from the world-axis perspective).
