Rail/mass-transit can suffer the same... I was once told that we... “cannot afford a braking syste that has four SILs, the maximum that can be afforded is two”... this was followed up by an apparently serious question from the buyer as to what a SIL is. There are too many non-engineers having authority over engineering decisions!

Too true.
I once worked on an inertial sensor to be built to SIL4 that had a required series production cost of UKP 1.79.
It was never clear whether the degree of creativity needed for that was greater in the software engineering than in the management-accounting.
