I think you see this through different eyes according to your experiences.
In 40 years of driving I've only had 2 bad(ish) accidents, neither of which would have been prevented by current technology. OTOH I've fixed vehicles maybe a 1000 times in the bush, side of the road, wherever. Many of those times I doubt I could have fixed the car if it was a new one and if it was an electronics problem the score would be 0%.
That said, If I'd been saved from injury or worse by ABS or other technology just once I'm sure I'd be a real convert 
For example I don't live in the snow/ice so see little advantage in having traction control, it's one more thing to break, those who do live in such climates may have a different view about the feature.
Of all the electronics "stuff" in a car, how much is safety related? Does anyone know?
I wouldn't be surprised if at some point we may see car-bus systems extend out to the periphery, i.e. turning light assemblies, etc. being powered by a common voltage bus but commanded via a CAN or similar RS485 communication system to save on wiring and weight.
Another thing we can't fix
