I believe the auto industry would like us to lease cars and have their network care for them. That in itself doesn't directly address if they are too complicated, but it does address some of the complaints about inability to service a car yourself.

Even the 90's cars are quite reliant on computers and all of those electronics are getting old.

The question might be restated as, "Are cars becoming a touch screen appliance now?"

Yes.
