My observation is that integration is a weakness across the industry. Some ground-up design/build, some choose the best off-the-shelf sub-assemblies — either way (and anywhere on that spectrum) nobody does a good job of fully integrating (which must include robust feedback upstream to make these off-the-shelf products better”).
TL;DR: tech in cars is becoming geometrically more complicated, increasingly less-understood by the OEMs, poorly integrated in its implementation, with broken feedback-loops inside a broken feedback-loop.
I’m curious how wrong I am from your perspective?
