I am an Automotive Instructor and our curriculum is regulated and required by our governing body. I do not have a voice in this whatsoever. The student will ask, “Which vehicles use this technology?” I can only respond truthfully. Once the cat is out of the bag the students get upset and then lose interest in the presentation. Without going in to detail of which components I am referring to, even the layman knows there is just no comparison from 1974 to 2012. I cannot even make a comparison to what we have now because we don’t use any resemblance of those systems anymore. I would have to teach my class as an Automotive History class and not Thermodynamics class. In other words I would not expect to learn how too manually hand crank a Model T in an Electronic Fuel Injection class. Only if the older information relates to the new information it can then be made to work. This is not always the case.
