Independent US License Plate Data Set That Is Available For Purchase/Tests?

Is there an independent License Plate data set one we can use for verifying OCR functionality of an LPR system? There are few university sites that have some plates, but they're not exhaustive. Does DMV offer such data set that we can purchase?

That sounds interesting. How would you choose the variables based on how the plate image was captured?

Have you considered writing a script to generate jpg plates from various license maker websites with all states/styles/years?
