In my experience at the DMV they process a large number of clients per hour; they appear quite efficient. The problem is that there aren't enough customer service agents to handle the volume so the lines are massive.

Cutting their budget makes things worse, not better.

Yes. I've been twice in the 9 years that I've been living here. Total time in the DMV in 9 years is under an hour. Last time I went, I spent under 5 minutes inside the building, less than a minute at the desk getting my registration done (I usually do it online, had a weird one-off situation).

I've never experienced customer service half that good from ANY corporation.
