Yikes. Really? Where do you live? I can’t imagine living someplace where I’m forbidden from picking up a wrench. Heaven forbid I buy some PVC pipe. Who knows what mischief I might get up to!
For the record, I do my own break pads. And have done the master cylinder (thing that powers the breaks) on my cars a couple of times. Not just without formal training. Without any training except what I could quickly Google.
Europe. When I lived in the US I saw cars with bald tires, clearly damaged frames, spewing insane amount of smoke &c. on the road daily, I'm glad I don't have to deal with that over here.
44 states have minimum tread depth specified in the law. Almost nobody has the tool necessary to replace a tire anyway, so nobody does that themselves. So what’s your point?
Not sure why you would assume that prohibiting people from working on their cars would increase the level of maintenance.
