The first and foremost thing I would change would be the Arizona Driving test! It must not be too complex or of much quality seeing the type of people who drive on the Arizona highways everyday!
It's kinda like having a bunch of monkeys driving on the roads! I mean, do you really need to cut across five lanes of traffic just to pass one guy as you realize your exit is in two miles?
Turn off your cell phone! Turn off your blinker that's been on for the past 537 minutes! Maybe turn your blinker on when you are changing lanes! Just maybe?!?
Get a new license system so 65 year-olds don't have the same picture as when they were 16. Just gain some common sense and courtesy! If I think you are a bad driver..you probably are, so get off the road already!
