hmm that might be because we don't use the DMV here in Texas the same way - TxDOT and TxDPS are the two agencies you're going to interface with to handle the stuff that California's DMV does.
I've been in TX 5 years now (and owned a car that whole time) and never even knew we had a department of motor vehicles.
Then New York.
Then Virginia.
The only results for Texas DMV are two ads at the top of the result listing for sketchy drivers-license.org type "businesses".
