Road rage

So my mom has major road rage... I mean extreme road rage... she acts like she's not afraid of anything or anyone but I am... I mean what if she yells @ the wrong person and they try to hurt us... not to mention the fact that most of the words she says when yelling @ someone aren't that Godly... I mean plus like what if someone like tries to follow us home or something... There are much crazier people out there and I know we have God's protection and everything but not if you're acting outside of God's will... I mean really... It kinda makes me sick and worried and upset with her... but I can't tell her because she doesn't want to hear anything from me... its not fair I mean she is putting all of our lives in danger... not just her own...
