[Batman] Why does Batman allow ranged weaponry on his vehicles?

This is NOT about Arkham Knight. It's well explained in-game why the Batmobile is a heavily armed tank.

But in any other circumstance, why does Batman allow guns and weaponry on his vehicles?

On similar justification as "anti-material" weapons used by the military; he doesn't intend on using them on people. The guns on the vehicles are supposed to be for other vehicles or other inanimate objects.

How each Batman does in terms of keeping to this varies from Batman to Batman. He has been known to give into temptation and shoot for a person, like when he launched a strafing run on the Joker during Tim Burton's Batman film.
