Geez... when you see the circuit boards that drive our cars it is scary. One of those components fail, the car may fail. Especially troubling since many cars are becoming drive and brake by wire.

From a simplicity standpoint, you're definitely right, naperlou. But automakers are getting concerned because some vehicles have now passed the 100-MCU mark, and many have more than 90 lbs of wiring. They want their vehicles to go on a diet, and integration seems to be the way.

Chuck, I find it interesting that the automakers are looking for more integration.  There is always a push and pull in this area.  Smart devices have their own processing power and the resulting communication is at a higher, simpler level.  One reason that many modern cars have tens of processors is that it is cheaper and easier for a supplier to build a subsystem with the smarts built in as opposed to having to install software on another processor.  One example I was given was the temperature sensor that most cars have today.  These typically have their own processor.  Even though even the smallest processor would not be busy, the integration is much easier.
