Actually, I had to update my wife's DL last year after we got married (Name and Address). It was kind of difficult because all the utilities were in my name, so we had to go to her bank and update her address, and then wait for the next bill to arrive. Then we had to make an appointment and instead of using the one in our town, which you can never get an appointment at, we had to drive down to Aurora to get one two weeks after I made the appointment.
(Our new Secretary of State is a moron, he's managed to truly jug-**** this system.)
So please don't tell me that it's "easy" to get an updated ID, if you are poor, have an irregular work schedule, or lack reliable transportation.
