She probably figured it would be too difficult for them to collect so they wouldn't bother trying. She doesn't own real property so they can't place a lien against that and get paid when it sells. She isn't the registered owner of the car (since she has no license or insurance) so they can't repossess it to pay the debt. She doesn't have a job where they can garnish her wages. They could maybe try to go after her Ad Sense revenue but I imagine that would be a huge pain and expense since Google is in California so the judgment would have to be recorded there as a sister-state judgment.
They could try to levy the bank account if that is in her name. I don't know what is involved in a bank levy in KY.
Damn you, Kentucky, for not providing case information through the PACER system.
