============================

  In a 4-d space environment -- the garage, the car, and the observer, all 
existing in the same time -- the garage and the observer might easily fit in 
the trunk of the car with an awesome amount of space inside to spare when 
the car is doing the significantly greater [relative] velocity.

  On the other hand, all being in the same 4-d space environment, and again 
all existing in the same time, when the car is doing a significantly 
[slower] relative velocity than the supposed "at rest" garage and observer 
(thus doing a relative velocity in the universe significantly negative to 
the above supposed ABSOLUTE of zero velocity (for the garage and observer)), 
then the car might easily fit inside the garage with the awesome amount of 
space inside to spare.

  Whichever is doing the significantly greater relative velocity is probably 
occupying -- all at once (all at one time) -- an awesomely greater dimension 
of space (attaining a different plane).
