Both diagrams say "garage" next to the red worldlines (the front
and back of the garage) and "car" next to the blue worldlines (the
front and back of the car), they are labels to tell you which
worldlines belong to which object. And in the first diagram you
can see the blue worldlines representing the car have position
coordinates which don't change as you vary the time coordinate
(move up and down the graph vertically), so that's the diagram
representing the car rest frame.

*TY. I'll look at those diagrams again. Incidentally, I just posted my
solution to the alleged length contraction paradox. I can't prove it
because there's no test possible, but I'm confident I am correct. AG*
Alan is like the guy with a map but can't use it because the scale is so
small he can't see himself on it.
