When was the last time you needed an airbag? I wouldn't be upset on _principle_ if it turns out my car doesn't have a working one; I don't even expect to use it

When was the last time you needed an airbag? I wouldn't be upset on _principle_ if it turns out my car doesn't have a working one; I don't even expect to use it frequently. However, when I do _need_ it, I'll need it badly.
