alt Hacker Newswhile I agree, there's many places where the compulsory car checkup is tied to your relationship with the mechanic. I don't think my parents ever had a "valid" car but the certificate always was. It never felt wrong (although I think it is) but more like mutual aid or service.
There’s also the fact that nearly 1/4 US states require no emissions or safety checks whatsoever [1]. So everything is valid by default and realistically the only thing stopping you from driving a literal rust bucket, with tailpipe dragging, poor combustion, or modified emissions filtering (like modifying your truck so you can roll coal down Main Street) is it a cop feels like pulling you over for it
