Because most snakes have a wider track in the back than the front I have wondered how the new alignment machines deal with this lack of "square".

Although I understand castor, camber and toe-in, I have trouble understanding how the modern alignment machines measure it. When the tech is hanging the whatevers on my wheels how do the gismos know that the track in the rear is greater than the track in the front? If the machine assumes the wheel base is square will I end up with a bad alignment?

Any ideas out there?
