I&#x27;d certainly be interested in hearing any more educated takes on Toyota&#x27;s use of global variables specifically or the auto industry&#x27;s capabilities in software more generally; I have no first-hand knowledge and am making a lot of assumptions (hence the throwaway, downvote away ;) based on generalizations I&#x27;ve heard about non-software-focused companies that end up having to write some code for their physical products.
