I have a whole rant about how consumer software and software for serious things (ie: people can die) need to be treated differently just like civil engineering and building a shed in your back yard should be treated differently. There is no room for agile code in a finished product where lives are on the line. Its fine for non life or death things and its a great way to prototype ideas. But the control system on your car should be developed with more rigor than that.
