Heck, in some states, DMV records are open to anyone.
Texas, for instance.
Woman hit me backing out of a parking lot, and dissapeared, not answering my phone calls or my insurance agents.
I looked up her plate number, found her address and paid her a visit, asking her when she was going to call her or my agent back, and letting her know if she didn't do it soon, she could also deal with my lawyer.
