Lots of data re vehicle registration and licenses to different groups. Insurance companies and banks are common but there are many others. Everyone from towing/repo people to Experian.

New York has a good FAQ. https://dmv.ny.gov/dmv-records/permissible-uses-personal-inf...
Some states are not so good at protecting data, or rely on an honor system: https://dfw.cbslocal.com/2013/02/11/cbs-11-investigates-your...
