How do modern cars regulate temperature so well?
Nope... Cajun VooDoo...
As mention they don't put any numbers on the gauges or they flat out lie to you.
The class 8 truck manufacturers used to use good old fashioned analog gauges so the DRIVERS of yesterday could take note of the temps and pressures and report any questionable numbers.
Today's STEERING WHEEL HOLDERS wouldn't know the proper oil pressure or coolant temp if it bit them in the ***. I drive a 2017 Kenworth with 505,000 miles on it. The gauges barely move, or are way off, because KW' s fleet buyers don't want their pussy drivers writing up non exsistant engine issues with every post trip DOT inspection.
Same with the car makers... accurate info would have the service departs swamped with nonsensical complaints about operating systems... everybody would think they own a new Corvette then come in and complain about back seat legroom.
