How long before they reference it with unpaid parking tickets, etc., and begin to use it as a revenue stream?

Are unpaid parking tickets an illegal offense? Yup. Can you have a warrant issued for not paying your traffic tickets? Yup.

And how is scanning plates, and arresting people who ignore the law is a bad idea? Criminals thrive on the indulgences of society.
