I read somewhere that the average gas-powered car has about 30,000 parts. Automotive supply chains have "Tier 1," "Tier 2," etc. suppliers and who knows how many chips are single-sourced for small factories without much buying power (or profit margin).I had word not to long ago that the automakers had bid up some smaller power components up by 25X. Not that big of a deal when the finished product sells for tens of thousands of dollars, however an issue when it sells for $800
