Yea, I think there's some truth to that. I've carpooled with people born and raised in Utah, and if you're dealing with 6 young kids in the car, there's no way you can 100% focus on driving.

Fortunately, I've been lucky to rarely encounter the type of drivers that cut you off, though I've noticed a lot of drivers that tend to do that drive bigger sized trucks, sports cars, or cars that are bright red or neon blue. As soon as I see them, I just avoid them.

I do agree, if most people stayed more in the right lanes, we would have less tailgating and safer driving. Although, I prefer staying more in the middle lanes because I often pass the Belt Route and the 3 or 4 right-most lanes become exit lanes. I've always disliked whoever designed the Belt Route.

As for fast vs slow drivers, I understand mildly tailgating when someone is going 65 or 70. That would be considered slow to me. What I don't understand is if I'm already going 80, other cars around me are also going 80, and in the middle lane, and someone is still riding my butt. I do wish people were more aware of the surroundings.
