> Are you seriously under the impression most of the computers in a modern car have anything to do with safety? I never said that. I said the examples pointer out by the GP post were all terrible examples to demonstrate too many computers in a car. Also ECU is Engine Control Unit. Your seat probably has a tiny microcontroller in it, MCU. And yes, your examples are all great examples of complexity that can break. Anti-lock breaks, bad example. Tire Pressure Monitors, bad example. Computer controlled LED accent lighting, good example.

So you agree with their point and just wanted to nitpick? I mean they're mostly right in their comment, a large number of people don't even know what the tpms light is (https://www.aftermarketnews.com/forty-two-percent-of-drivers-cannot-identify-tpms-warning-lights/ https://www.aftermarketnews.com/forty-two-percent-of-drivers...) Climate control is a largely overcomplicated system in many cars, using everything from humidity sensors to skin temp scans and then refusing to work when any one part stops working Adaptive suspensions have left entire generations of vehicles pretty much unusable as they slowly fail and essentially "total" perfectly good cars Even if they're wrong on one or two counts, the point is clear enough... - Also anyone who knows cars knows when ECU is referring to an Electronic Control Unit from context... It's been a few decades since anyone really got confused by that one. The ECU in charge of the engine in this car is called the "Digital Motor Electronics" ECU or DME. They are proper ECUs with a lot more complexity than a single MCU. Every single one is a node interconnected with separate firmware versions that need to sync up in certain ways. The DME in charge of the engine is treated with exactly the same as the ECU in charge of accent lighting when it comes to manufacturer tooling, the tooling simply enumerates over these ECUs and provides an identical interface to them.
