I&#x27;m assuming the development process for embedded auto software like this would be pretty rigorous, meaning it would be fairly difficult to sneak in code like this.<p>I also assume that testing of emissions software like this would involve a lot of lab&#x2F;road testing with the vehicles against the EPA test profile and therefore a lot of people would be involved. Suggesting this is the stealthy work of just a couple of software engineers is very hard to believe.<p>Can anyone who&#x27;s worked on embedded software in the automotive environment comment?
