Yeah I hear you. It's just that from my point of view it is hard to sanctify the engineering community when learned companies such as Ford are manufacturing truck where the (cast aluminum) fuel pump driver is bolted to the frame crossmember (steel) under the truck bed over the spare tire........where it won't ever get dirty or salty.....ever.
I have a high school education. No more.
I know that you cannot put steel alongside aluminum without penalty. Don't tell me that the wise and learned engineers at Ford have forgotten high school chemistry? Who pays for this (deliberate) idiocy? You the consumer.
That is only one of hundreds of examples I can cite, and the natural result, for a thinking and observant person, is that Engineers are working at their best guess (just like the rest of us) worked out to a more extreme decimal place. No more.
My apologies to any engineers here. This is not personal.
