I'm still not quite convinced.........every time I'm driving and I catch a whiff of a vehicle running rich, it is always some pre-1985 vehicle which likely is carburated. I'm not saying it is not possible to make it run correctly and burn a proper mixture, but it takes more time and maintenance. Yes, there are ways of mechanically fuel injecting vehicles as you say that date back to the 50's but those systems were complicated and lets face it, mechanical things need maintenance.........and often lots of it!
The equivalent mechanical system required to do all that a modern computer controlled vehicle is doing would be a) costly b) complicated c) unreliable and d) if not maintained very inefficient
If all the vehicles on the road today used strictly mechanical systems or electrical instead of computerized for fuel and ignition there would be far more breakdowns, lower fuel economy and more trips to the mechanic.
With a computer controlled fuel injection system you have eliminated 90% of moving parts associated with carburetor failure. No matter how well something is built, if it is mechanical eventually it will fail. If it is built so well that it will never fail, nobody could afford it!
Now.........having said all that, I do believe that computers in vehicles are in places where they should never be. They should never control your brakes, your throttle (just ask Toyota!) or your basic systems like lights, wipers, heating/cooling, steering, suspension, your radio and the security systems in many vehicles is way over the top! Heck, even the fuel gauge is run through the computer in my '98 Silverado...........but we won't even get into that!
So in some ways I agree, in others I really disagree.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
