I'm not saying you do, but I have found the general public vastly underestimates the intelligence of many auto mechanics--especially today's mechanics. I guess they have always been an easy target in movies, etc.? I have a feeling your dad could learn anything if given the right structure. Mechanics are underpaid, expected to continually learn on their time, provide $20,000-30,000 grand worth of tools; and the owner…
Once-upon-a-time-time auto mechanic, long time software dev here. It's not just the owner making a living, when I was active it was a decent middle-class living (25 years ago, could be different now). I'm talking professional, can diagnose your problem without throwing parts at it, owns a torque wrench and knows how to use it, not the vocational school students you find at Jiffy Lube. No one I knew was making BMW pay…
That's an interesting comparison - why couldn't you use StackOverflow for mechanics. I don't know anything about cars other than they have generally have 4 wheels and use fuel but from the hardware work I've done on computers whenever I was troubleshooting stuff I would first look for symptoms then I would search and find random things to try on the internet. I don't see why this wouldn't apply to cars - people sharing their cases and being able find relevant ones could be a time saver.
