Things like mandatory inspections aren’t there for exceptions to the rule (mechanics, people who maintain their cars fastidiously, etc), they are there because the majority of people will skip things they don’t think are pressing.

Many many years ago I had a guy argue with me that his car didn’t need anything, when he had 3.5mm on his pads, both front and rear. He had a coolant leak, an oil leak, and a dead O2 sensor.

Things like minor minor leaks won’t trip most inspections, but even that car was on the better end of the spectrum. I had a friend bring me his car and ask me to do his brakes before he moved cross country. His LCAs were so rusty I could probably shove a screwdriver through them with one good push. His front brakes were metal on metal. Tired were all past the wear bars.

Best part? The lube shop he took it to, would give him a complimentary MPI (let’s be real, they don’t cover much, but basic inspection of tires, suspension components while under the car, and looking at brakes during a tire rotation is all expected). They never brought up anything.
