There was a peer-reviewed report published in the journal for Applied and Environmental Microbiology that studied the amount of bacteria that was blown from hand dryers in 36 public restrooms at the University of Connecticut School of Medicine. The sample from the study concluded that as many as 60 colonies of bacteria were blown from a hand dryer in just 30-seconds. A number of those bacteria were linked to fecal and human bacteria, even bacteria known to cause serious infections.
Why YSK: So that you are informed for your own health, hygiene, and wellness and to prevent further spread of more harmful bacteria.

i like this idea a lot and perhaps people would wash their hands more if the fact that walking past them and not doing so would broadcast the very fact they dont wash their hands
There is a bar/arcade near me that has their sinks right outside both bathrooms in full view of all the patrons, and I think it would definitely encourage people to wash their hands since everyone can see you leave the restroom, especially considering it’s a place where people are touching everything
