I don't have any particular take, the only thing I can say is that 60-100 computers in a car is lowballing, the new average is about 130.

Are they necessary? Some of them yes, for example the ECUs that manages the towing hook manages the brakes and signaling lights for the towed vehicle or trailer, making it a far safer experience.

Some ECUs are there simply to reduce costs and prolong the life of components: an ECU that knows when and how to go in deep sleep will make your car battery last much longer (and i'ts a huge thing in automotive, I had to work three montsh with other 20 people to reduce sleep consumption by 20 microamperes).

Most ECUs are needed to prevent fires, 99% of the work the components I am developing these days is to properly cool the engine, ensure proper cooling and in case of malfuction issue a red alert to the engine to either stop the functioning or activate a low heat "limp home" mode.

Other ECUs are needed due to always more stringent laws: in the US newly manifactured cars are required to automatically issue an emergency call when a crash is detected, which sends the GPS location of the car. That means having to integrate a Internet connected ECU to the car, with usually two different processors on the same board segmented in such a way that a breach on the Internet facing one will not become a source of commands in the main bus of the car, which is also (but only recently) segmented to accept certain messages only from certain sources.

So yes, too many ECUs with too much cost cutting and a production culture that has zero capability of managing complex computer system make for cars that as of now are quite rickety, with the caveat that while rickety old cars killed people new cars kill themselves first.
