That is scary, thanks for sharing. And for those here who don't seem to be worried about the safety aspect, note that this means any corporation with a lot of your personal info (insurance, Equifax, etc.) could just submit a FOIA request to get the license plate number of anyone in Illinois (and likely other states) who's parked anywhere illegally, whether intentionally or accidentally... and then strike a deal to gather license plate scanning data to track where you go and what you do. Heck, I wonder if this sort of thing is already happening and we just don't know about it.
I think, because he glossed over it in the post, that you are underestimating how much work Matt does to get the data & how much the governments he works with try to hinder & redact it.
In some cases that is a very good thing. In other cases it’s just them trying to obfuscate and block transparency.
