Uhh this seems like a big fact to gloss over, and something I am quite surprised by. Could you point to any examples as I’m having a hard time finding anything available publicly from any DMVs/states
In Michigan anyone can do a in-person plate lookup for about $15 and it comes back with complete registration information including name and address. VIN and car details as well.
The $15 makes this pretty hard to scale too. The link someone posted was $0.05/request. I'd love to see how/where you can get this data in bulk from a primary source.
