The US regulates "wear bars" on tires, which make it a lot more obvious when tires need to be replaced.
I'm not saying that government regulation is needed, I'm just pointing out that the purpose of this tire feature is to make it more likely that people notice tire wear, and don't die from accidents involving bald tires.
Ah thank you for the clarification. I was thinking along the lines of a right to repair where maintenance tasks such as replacing filters are convenient. I would not attribute that to regulation as much as practicality in even mechanics working on the cars.
