The only pitfall to raising the speed limits-and why I would oppose that move, is because many people are just absolutely determined to drive faster than whatever the posted speed limit is. 20 mph in a school zone? They drive 30. 65 on the Seward (or Parks) they drive 75. If we raise the speed limit to a "realistic" 75, people will drive 85-90. People feel they have a right to go "5 over" (or 20 over) and not get a ticket.
