I wish it was the standard! It's not anywhere near as commonplace as you suggest in the video, even now almost 2 and a half years after you made the video!<br><br>You see, I live where there is a factory behind my building. It's all I see when I look out of my kitchen window. There is a 20 foot wide strip of grass then an 8 foot high fence and just beyond that is the delivery road of the factory. Not once in a year and a half of living here have I heard any of the delivery trucks that reverse along that road using the white noise warning system. ALL use the old beepers. There is a truck that sometimes delivers groceries to someone on my street that uses the white noise system but that is the only one I have heard!<br><br>Curiously I have heard more of an odd reversing warning system than the white noise. This one has a male voice repeating "Caution, vehicle reversing" which makes me wonder why, in a multi-cultural country that has residents who can not speak a word of English, would you have a reversing system of this type! 0.o
