Seemingly a reasonable recommendation for an alert signal. However, there are alert signals for other events. So, the "lateral collision detection arm" goes off, and then I'm thinking, "what the hell is that for?" and wondering what I'm supposed to be looking for rather than simply being attuned to what's around me. As an example, those who have vehicles with the "blind spot warning" in outside mirrors (with or without an audible) tend to become immune to the signals and find little value in them.
