Bullets are a bad example because they have multiple properties which makes them much harder to localise than many other sounds.
I'm pretty sure most people can localise a vehicle emitting broadband noise (engine or white reversing sound) in the conditions that matter.
As the other poster mentioned, the characteristics of sound matter. That’s why the report of a firearm is a bad example.
But there are more commonplace examples. Older phone ringtones are often hard for people to locate, but nearly everybody can pinpoint the sound of a dropped coin. Sound perception is more complex than just perception of pressure levels. To the point above, you wouldn’t confuse a car honking in front of you with one behind you even in the presence of ambiguous ambient noise.

I'm not talking about the report of a firearm. I'm talking about the physical impact of the bullet on the armored vehicle you are in.
Also I have no idea what you mean by "but nearly everybody can pinpoint the sound of a dropped coin". What sound does a coin make when it is dropped on a busy street?
Ask anyone who's been at a shooting in a city. Everyone gives a different answer for where the shooter was at. It's such a severe issue the US Army has microphone arrays they equip urban combat vehicles with. Even with bullets actually bouncing off the armor the troops cannot accurately locate the direction of the shooter(s).
