There aren't many, but here's one of 'em:
I stood in line at the DMV for approximately 10 seconds. The lady looked at my info, entered it all in, gave me my new plates and registration, and I was out of there in less than 10 minutes.
Surprisingly, this is not limited to today. Last summer-ish, I went to the DMV to get my new UT Driver's License. I had the same experience there, although it was a different office.
My experiences with California DMV's equated long lines, multiple crowds, rude employees, and frustration on end at all the hidden fees.
I am now having a great day!
