A Quiet Man

I am traveling to Washington, DC on the Acela, in the Quiet Car.

What does that really mean, to be in the Quiet Car?

The man opposite me very quietly took a call on his cell phone and apologized for it, but made no attempt to cut off the chit-chat.  For the last half-hour, he has been snoring in that wheezy-wheezy-then-full-throttle-eruption-of-noise that could be grounds for divorce.  Is that quiet?

In the Quiet Car, does a person have a right to involuntary, grotesque bodily functions while unconscious?  What about if conscious?  What about if concussed?

The fight for the soul of the Quiet Car is NOT just about cell phones and electronic beeps anymore.
