Isn't that the ultimate shit hitting the fan (of the car behind you) issue? Why not go direct, like the trains of yesteryear, "kindly don't flush while the train is in the station". I'm with Sully.

Why in the world do you feel the need to install a complex, unnecessary and possibly ineffective system to an already complex potentially unreliable
