Maybe the article could have included that if an automotive engineer had written it. But I think the article is perfectly fine for having included the steps that it did address.

Think about it this way. If you wrote an article about preventing the Toyota bug that resulted in uncontrolled acceleration, unless you were a former Toyota employee there's simply no way you can say "Toyota needs to change these specific lines of code" and you wouldn't even try. You might say "Toyota needs to adopt such-and-such code review practices" or "NHTSA needs to regulate the computer-controlled components of cars like this". Those are early, indirect steps that should force (or incentivize) the actual detailed improvements that you'd like to see happen.
