I am cursed because I do have mechanical sympathy, I used to regularly wash and clean my cars, keep the tyres pumped up weekly, don’t idle my vehicles, checked the oil and coolant regularly, have them serviced and maintained on time, however despite that I’ve had more bad luck with expensive repairs and accidents than most people I know.
I meticulously looked after my last car, the paint still failed on the roof, I punctured two expensive tyres a week after fitting them, an injector went and flooded the sump with petrol which cost 800 quid, the gearbox broke at 60k miles and needed a 2 grand repair, then a month later it was crashed into and written off.
Then my colleagues who take on expensive lease cars and never check a single thing, let their tyres go bald because they never have MOTs to remind them, miss their required services by thousands of miles and never check a single thing themself just trundle along in a stress free motoring life without worrying about anything then hand the car back after 3 years and move onto the next one.
Sometimes having mechanical sympathy doesn’t actually gain you anything hence why people don’t bother learning it.
