If this is real I would think there would be a ton of people stepping out of their houses, looking out the window, stopping their cars to get out and listen, stopping on the sidewalk dead in their tracks, etc...especially with this sounding so incredibly loud? There's just one guy interested enough to open the window and look out? Just seems opposed to typical human nature is all I'm saying. A whole freeway will slow to a crawl because people are slowing down to look at an accident that happened on the other side of the freeway.
