I agree that that's a problem, but there are still an awful lot of 90in90 or less maintenance (rather than repair) tasks on a car that require no diagnosis abilities. E.g., oil changes? They cost way more of my time to take to an oil change place than it takes me to run my car up on ramps and do the job myself. Extra bonus that I don't risk some minimum-wage wrench monkey stripping the drain plug bolt on my car.
