You realize the law can just make shit up, right? It’s very easy to make a law that says “ALPR data needs a warrant” without impacting the ability of people to record in public. You just need to clearly define ALPR, which isn’t hard.
Yeah, but we don't want cameras everywhere, not just auto plate readers.
What is the difference between a security camera watching the municipal tools shack entrance and the security camera watching the main road?
The ultimate goal is to not have a massive database of everything that happened everywhere going back forever. So it even extends far beyond just reading license plates.
You don't even need to define it - you can half-ass it and rely on courts to clarify the edge cases. That's how the vast majority of laws work.
