Yeah, my wife's Fabia is (switchable) stop/start with (switchable) DRL and driver "aids" and "assists" and VW complex computer systems and programs, but no, thank gawd, not as much electronic and convenience gubbins as a 2024 car so the battery needs less preventative attention than your 2024 to get your battery life passed the VW 4 years (5 for my wife's car). Surely laptops you plug in the mains! 😁 With the laptops my wife has and had I've noticed a battery power indicator and warning by nothing about health but they were s/h old when she got them, I've no idea about the "smart" (they're not) phones, they don't like me and I don't like them. The dual gauge I pictured is "mechanical" rather than electric on water temp and oil pressure, oil pressure is responsive quickly moving around to a certain extent with temperatures and revs, coolant temperature usually less movement plus pinch of salt accuracy (factory tested at the two sets of dots only). 70s temp gauge is electric two wire as you put, sender and gauge so two points to stray with. As I used to tell me wife you treat them as gauges not "accuracies", having put that the fuel gauge and sender on my last "classic" was more accurate that her at the time brand new modern car (that the Fabia replaced. Before my driving time (late 70s) car batteries need charging and about 60 years later we're back to that. I seem to be the only one to remember (so perhaps on Fantasy Island) that in the 60s electric cars were "he future", and of course electric cars were about before the ancient petrol and diesel puffers we run about in now.
