Okay, I know this subject that is not quite suitable for civilized discourse, but this has to be said: the absolute worst new technology development is the autoflush toilet. Seriously, there has to be a better way to accomplish this goal than having an electric eye try to determine when my ... backside has left the seat.
And, as if having an electric eye watching you go to the bathroom wasn't bad enough, my experience is that the damn things almost never work properly, which of course leads to a lot of wasted water.
