Photons work better for driving a car too but being able to hear is still quite useful.

In other words: we already have lots of things that measure photons. You see things on two totally different media it's a lot more compelling than just one.

That may be the case, but it doesn't explain why neutrinos would be essential for intergalactic communication. Maybe the person I was responding to didn't realize neutrinos travel very close to the speed of light, not infinitely fast?

Neutrinos are not an analog to sound in the point you are trying to make. They are many orders of magnitude more weakly interacting and much, much difficult to measure.
