That second one is creepy. I wonder how many actually hear it. I was once being paged at an airport but never heard it because I tune out certain things. I think that most would be so focused on their here & now that the second audio would almost be almost considered a audio subliminal message. As for the talking window, my 1st thought was who would want to put their head on a dirt window. Germ factory.
Clearly you've never been on mass-transit subway/bus between 5-7pm. Aint missing much cept bad smells, kids who say "like" in every other sentence etc. I get weird looks from pulling my hand into my sleeve if I have to hold onto a rung or post.
