I've driven in lots of different states and Utah is no different than the rest for the most part.
However there does seem to be one trait in Utah that drives me absolutely bat**** insane... people drive like they are the ONLY ONES ON THE ROAD. I have a few friends that think the roads are theirs only. I watch them take 2 miles to accelerate to 40mph and drive 60 on the freeway in the left lane. I just cringe when I look in the mirror and see cars stacking up.
I've just learned to drive like an *******. I pass on the right and use the carpool lane for passing if I have to. Hasnt bit me in the ass yet.
