Absolutely spot on, what I've posted on various car sites before. Well done. Vast majority think engine oil and engine and transmission are the most important things when they're much lower down the priority. The old (British) MG slogan used to be "Safety Fast". I can't really moan about any safety features but a lot of the bottom-wiping stuff that goes on with modern cars does seem to encourage disengagement of the human brain and being more of a passive passenger behind the steering wheel. I'll put my usual for other possible fresh viewers, importance - brakes, steering, suspension (all three include tyres), safety electrics (lights, horn, wipers, blower, etc. and clean reflective number plates) see and be seen. I don't want to downplay safety at all but don't get too paranoid and skittish about driving (you can leave that to the underdeveloped car computer systems and driver "aids" and "assists"). Decades back when I first bought a car and when about to sell I would spend two days cleaning and polishing it, wheels off, seats out, under wheel-arches, boot, engine bay "detailing" and as my cars were almost always outside cleaning and polishing them reasonably regularly and before any club events - now I clean the lights, exterior mirrors, numbers plates, rear window, other windows as required, and that's it other than perhaps a clean once or twice a year, modern paints hold up so much better now. In case you've not seen 12v battery is particularly important for less-trouble running, (very) occasional (or as required) preventative charging often best done with a suitable charger maintainer, following car and charger instructions, at a low 3-4-amp, slow rate, over more than one session if required, to battery full (not around 80% as car's BMS has it). You're well set, you could offer some help to others already (including those with decades more driving experience and longer model ownership than you, probably including me). Cheers.
