There are no absolute frames with special properties!

How does light now at what speed to travel ?

From another post:

universe, at a reasonable distance from some
concentrated mass, it immediately adjusts to a special
frame, the photon's speed is immediately set by the
masses of the universe that surround the photon.

Why does it need to 'know' anything .. it just does what it does. How does
a train whistle sound-wave know how to adjust its frequency so that a
stationary observer hears a different pitch?

Light doesn't make a choice--it only exists propagating
at the cosmic speed limit. Not an iota more or less.
