Right: it’s not conceptually complex and Tesla, as i mentioned, shows such.

The parent comment to which i replied was listing significant systems in an EV, and hadn’t mentioned thermal regulation.

BMW’s outsourced Vitesco (part of Continental Power Trains originally) design differs in engineering (materials, components integration), with more disjoint components and more components therefore needing interconnections, and had cars (service bulletins applied to thousands) across Finland, Germany, Canada, US, UK, failing and leaking in a juncture not present on the Tesla design.
