> I mean yes in our world, but also no, the bottleneck if the universe is literally the speed of photons.
Not literally, no. The bottleneck is the speed of things with 0 mass, of which the photon is just one example (as far as we know).
I also think it's very likely that, had there been another force that was ubiquitous but carried by a particle that traveled at 200 km/h, that would be easier to detect than photons or happened to have other favorable properties, we could have easily evolved to detect that instead.
