So maybe 5-10 people max in the whole company would know about it.
Wow, only 5-10 people?
There are way more people involved in anything than that. People determining features, signing off on features, designing the wheel, ordering the wheel, QC'ing the wheel, updating the wiring harness, updating the service documentation, updating the parts catalog, updating the VC controller, updating the gateway code, updating the UI, testing the software, testing the hardware, testing the car as it comes off the line, etc. And then all of their managers. Yeah, no there are way more than 5-10 people that knew about the heated steering wheel.
