> Yes, I'm sure most people on this website have ran into seemingly bad design choices which made sense once they knew more context. But that doesn't mean that all bad design choices are like this.

I'm literally just saying the yin to this yang. Just because you run into a design that feels malicious doesn't mean that it always is.

Again, sorry for the sin of trying to make an analogy/example of something I'm not an expert in. You can rest easy at night knowing I'll never do it again.

You also pretty neatly laid out how re-using an existing design meant for a different car leads to some benefits to the end customer. Sure the full cost savings don't ever make it to the buyer, but there's still net wins in not spinning up new manufacturing processes (as you say). So I'm not sure why you're coming at this so combatively? Because I dared float the idea that maybe it's an engine efficiency thing we're unaware of, instead of part re-use cost/lead time efficiency improvement? Again, sorry for stepping outside of my lane...
