Yes, you simply find the hidden license plate camera, then figure out who owns it (I suggest social engineering technical support lines with the serial number). At that point, you can write them a letter that includes a ton of your personal information (which they "require" to match your license plate number with their database records).

At that point you have the right to ask them to delete their copy of the license plate record that they've certainly already sold on to a network of dozens of fly-by-night data brokers, malicious foreign governments, the police, and so on.

What they've already sold may already be out there, true, but more importantly the ccpa gives you the right to opt out of future collection.

Shotgunning the request to the major players may not give 100% coverage, but I think it would at least reduce the amount of identifying information out there which seems like it would be better than status quo.

I'm curious if anyone has tried this at all.

If too many people opt out, they just set up a new company and boom! No one has requested they get rid of the data or not collect it.

Opt-in is the only way to make this work, and that's why it will never get passed.
