This is a great point, one that comes up often when looking at 6-10 year old cars - replacing tire pressure sensors. The system is a great idea, but once the batteries in them little suckers wear out, it can be an expensive proposition to replace them. The aftermarket is stepping up, but I had a Lexus that the dealer wanted $600 for 5 new sensors, swap them out, and associate them to the car's ECU.A guy buying a new vehicle which he unloads after a few years, might consider certain items as "advancements". On the other hand, a guy (often me) buying the vehicle later down the road, might be cursing those so called "advancements", lol.
Now, this issue isn't the end of the world - it's a little orange light on the dash, and we somehow survived for decades of automotive operation without such warning systems, but not the same for emissions sensors. Throw a CEL, and you can't pass smog in many of the places that have it. Fortunately, the newer systems are usually very easy to diagnose with the proper tools - in the case of Fords, the tools are very inexpensive yet extremely capable. There are still some issues, or combinations of issues, that can make diagnosis difficult, and intermittent electrical/electronic problems have a greater impact compared to the mechanical control systems.
The bottom line is there will be a market for good diagnostic technicians (mechanics) for the foreseeable future. It's just a different skill set and array of tools... if an old-school Diesel guy like me can learn my way around Forscan and canbus systems, anybody can.
