I've had a wait of more than an hour both times I've actually to go to the DMV proper rather than a tag agency, but the employees were pleasant and on the ball both times, there were just a hell of a lot of people in there. If anything, that's an argument for expanding the DMV.

And, honestly, the private-company-on-contract option would probably cease to exist once a single-payer option existed. Right now there just aren't enough people on government payroll to justify building the infrastructure instead of contracting out.
