1. Step one, file claim in small claims court, get your money back / recorded action against the towing company / etc.
2. Carry a tyre valve removal tool with you. Whenever you see one of the offending companies tow trucks parked, and either unoccupied, or the driver is distracted, remove the valves from as many of the trucks tyres as you can.
This shouldn’t damage the tyres, unless they are left deflated for a long period, and it’s extremely inconvenient.
Also allow the use of force in defense of property wrongfully seized.
Will not end well. The more aggressive towing companies in Atlanta send their operators out in pairs, wearing mirrored sunglasses, body armor and carrying sidearms like they're mercenaries. You're outmanned and outgunned.
It's like they know they're engaged in business that might upset people or something.
The police, with all their training, still shoot civilians accidentally. I really wouldn't want to test the how-not-to-shoot-civilians training of some wannabe-Blackwater towing goon.
You have 2 choices. The first is the "always do it yourself" fix to other people's mistakes or intentional trespasses. The second is to have the "people in charge" do it for you in a sustainable manner, at scale.
The second option might include repeated litigation. I have no idea how it would work but making them pay more than they earn every time is a strong deterrent.
You win the game by controlling who gets to run as a candidate. That way, no matter who wins individually, you still end up with a majority in the legislature who will support policies friendly to you. And you don't need 100% control; some dissenting candidates need to be allowed, to provide an veneer of legitimacy to the process, but not enough to actually sway the votes in Congress.
Is a functioning democracy a right or a duty?
Or I guess you can just complain and post comments.
If you've ever been to a city council town hall, or read a local newspaper in an area where it's a problem, this is brought up regularly.

I don't see any handouts or special interest groups here.
I will assume that a flagged car will always be impounded when found. I guess that's the point of flagging it.
If your car was impounded because you were flagged without breaking any rules maybe you can address that somehow. Since your registration was paid up, flagging you car seems excessive, especially when it was just as a "reminder". There must be a way people don't end up in this situation for a "reminder" flag. So you can work on your side to make sure others don't get flagged unless their car really needs to be impounded.
Unless you were you supposed to update your address and check in with them to remove that flag, especially before leaving the state. In which case some more care from your side is required.
I'm not saying "privatizing law enforcement" is good. To a hammer everything looks like a nail and when you pay that private company "per nail" you can bet that's what they'll find at every corner. But you can always grab the issue from your end and try to do something about it. Otherwise next time you might as well have the Police impound your car and pay them for the ride. Same difference.
