One thing still drives me .. and others ...crazy though .... particularly
with mechanical engineers. For some reason, many have an "invented here"
philosophy and refuse to re-use time proven designs. This results in labor
cost overruns and usually a new, unproven brain fart for a mechanism or
something that has already been proven not to work.

Absolutely! I've got a group out west that I do a lot of tilt-up
structural engineering for. They do slipform huge feed processing
mills. If you give them a proven damn good design and they like it,
just try to give it to them a second time. They will reject it usually.
Sometimes I have to put my foot down, that's for sure. If any of my
structure has to attach to their slipform, I have to make a connection
that will slide because their mat slab and slipform settles usually 3
or 4 inches immediately because of the weight of the thing vs. soil
compression.
