 | Various experimentors have measured the speed of light to 9 or 10
decimal places or so, and it's always the same for everyone to that
accuracy. Since they did it at various times of year, and the earth
moves around the sun at about 0.1 % of the speed of light, that's
pretty impressive.
How would you like to have to measure the speed of sound to 10 place
accuracy, by doing it on a flatcar whizzing around through the air in
various directions with respect to your instruments, at 0.1% of the
speed of sound?

Relative to the source.
Nobody has ever directly measured the speed of light in a vacuum from a
moving source. Nobody. Ever.
