For the little it’s worth: cars are mostly computer now.
I come from a family of mechanics, my grandfather lamented new cars and their electronics because it’s harder to repair, he doesn’t try to understand the reason why, just that it’s harder now because the manufacturers “did it to him” to prevent third party repairs.
You can argue that the electronics are to prevent cheaper repairs, but there is another truth there: the ECU is an almost required component for decent fuel efficiency.
