And the DMV (Department of Motor vehicle Services) has also sold registration data. In California, and Texas, they have been fined for this - I'm unsure they aren't completely barred from using a loophole to still do that.

This is why I'm a vocal advocate for having an LLC own any vehicles you might drive. It protects you from the license-plate reading lookup as well from Flock et all. Though I don't know it guarantees you can't be looked up by insurance it's resistance by one more bit of friction. The vehicle I drive now is an old 2012 Lexus owned by Montana LLC and it also has no smart technology and very little insurance costs.
