If the sirens are at your back, you don't want that robocar to stop and hamper the traffic but to choose a side on the road/street to either park or continue its course until there is room to be passed by the emergency vehicule.

Blaring sirens can be easy to detect, doesn't mean the reaction should always be the same.

[1] preferably same as other vehicules which are possibly blocking traffic for emergency vehicles.

Sirens are designed to have an easily discernible doppler effect; a siren coming at you sounds different from a siren going away, which sounds different than a siren keeping pace with you. And furthermore, a siren behind you sounds different from a siren in front of you.

Human drivers generally manage all of this fine. If computers can't, then they aren't ready to drive.

It's ML, so I imagine a decision like this isn't hardcoded to begin with.

Directionality should also be easy to detect. Should just need a handful of mics around the car and some basic audio processing.
What I meant is that detection is one thing, taking good decisions is another.
