I speculated my ideas of why this is so:
Seriously. I have a theory about the aggressiveness of Utah drivers. It has much to do with the Mormon superiority complex combined with the conscious suppression of aggression in other areas of life in order to appear more spirichul and Christlike in front of their peers.
I could be wrong, of course.
And now I have another possible theory. Men with priesthood powah rule in all things, yea, even the highway. Women drivers, sensing this and how very wrong it is, step up their aggression a notch in the one place they can anonymously do so. Not like they can do it at home with their priesthood-wielding man, right?
Regardless of the reason (hell, it could be a combination of all three we've speculated on - Pants said that perhaps the Utah drivers are so righteous they know nothing could possibly harm them), the sad truth is that Utah drivers suck eggs.
I suggested that she create some bumper stickers to sell in Utah:
Let your light so shine, even while you drive, asshole
Praise to the Man who communed with his road rage
Let us All Press On in Cutting Each Other Off
Will You Drive This Bad in the Celestial Kingdom?
~~I thought of a few more...
God be with you 'til you speed again
Have I Done Any Good on this road today?
No garments? THAT explains why you're driving the speed limit!
Forgive me, brothers and sisters, I'm late for a(nother) meeting!
I don't cut people off on Sundays, so back off!
I am your chance to practice Christlike love and forgiveness.
Any other bumper stickers you can think of?
