85 MPH speed limit sounds good.
Personally, I much prefer the German autobahn system. You can drive much faster, but they enforce the rules in a far more intense manner with really tough cops and very fast cars.

They even have cops at the Home Depot equivalent to ensure that you are not overloading your car / trailer and becoming a traffic hazard.
