I mean if you hear noise you can instantly know from where you hear it, you can most of the time know if the car is moving toward you or away from you and you know if it is close or far away.

If you see a laser on the road then you don't get any instant information, what if there are more then 1 car and project light.

Anyway I meant that sound in general, we can instantly know where the sound comes from and we do not need to actively think about it.
