I think many of them inherently distrust the electronics, so it has been a real uphill battle for them to port some of their existing knowledge to these new systems. As to the computer system being the fault detector, well, I guess that is kind of all of us Techies fault. Built in diagnostics for complex systems is a lot of overhead, and of course the reading of the actual data may or may not be helpful without a deep understand of how all that information relates to the system operation. The first answer is of course to have a computer crunch that information, and with the early car computers, the crunching power is not there. Today, I don't think that is true, but history holds us prisoner sometimes.
The fundamental operation of a hybrid may be primarily electric, or primarily gas. This view will determine a lot how the parts interrelate and how the system overall operates. Other decisions, such a regenerative braking, dynamic power allocation, Battery leveling and other design choices will also affect the interrelation of the controls. And then there is the aspect of multiple computers. Some cars today have 7 computers that I know about. Which ones do what, which sensors each reads and how they share and manipulate information, if they do at all, also makes a huge difference in diagnosis of any issue. Some of these issues will self resolve over time as designers, engineers and mechanics gain familiarity with what works and what doesn't. Over time the solutions will cycle from complexity to simplicity while performance and efficiency will help form the engineering boundaries and comfort, and customer perception will help form the accessibility, reliability and aesthetic boundaries. In short the rate of change is accelerating ;-) But where the **** is my flying car???? I want one that shoots down drones and is stealthy while offering me full internet access. 100mpg wouldn't hurt either.
