Random thought: If you stick a very small adhesive mirror to the outside window before boarding, then footage "looking down" at the regularly-spaced railroad ties could contribute to information about the current speed and acceleration.
Well, on a straight section anyway, if you turn, the inner/outer edges will appear differently-spaced...
Wouldn't do anything positive in terms of suspicious staff though. They might think it's like some kind of heist-movie that will involve a specialized glass cutter making a circle on the window.

- Terr_ 2mo agoIn the presentation they mention they are using GPS, and also an accelerometer.
