Make camera roll match head rotation?

I'm making a driving game, and I noticed that when the car flips over and you're in first person, the camera does not flip at all and the Z(?) rotation stays the same. What should I modify in the default camera scripts to achieve the effect of the camera matching the head position while in first person? I know about Camera:SetRoll but I don't know where in the default camera scripts to apply changes.

Heres an image example of what I'm talking about when I say the camera doesn't rotate: https://i.gyazo.com/fc8e0e5e27e751e71510a4f29dc38177.jpg
