A question for the snowbirds

I live in Southern Arizona, and we see many seasonal visitors during the cooler months from colder climates, AKA "snowbirds." We welcome them. They are wonderful people and an important part of our economy.

I've never been able to ask this question personally, so I'll post it here. In Wisconsin, Illinois, Michigan, is it customary to drive 10-15 miles per hour below the speed limit? Or do you do it here simply because you're unfamiliar with the landscape?

Serious question.
I don't know.
but the question concerns me. Are you the guy riding my *** on the freeway? If so, I'm about to brake check you.
