Driving experience

I have been stating lately that, by watching the drivers, the word Prius must be Japanese for Prick.  Yes, it is my feelings that a good population of Toyota Prius drivers seem to drive like pricks.  They seem to have this "holier than thou" attitude.  This is not only true here in Salt Lake Valley, as my sister in law from the Bay area of California agreed with my observation.  Yesterday I saw this bumper sticker on Prius that only upped the ante, this one obviously has evolved to a new level of prick, here is that bumper sticker.  Brings "holier than thou" to a new level.

Now don't get me wrong, I have nothing against being fuel efficient, or economically minded but do you have to be such a self righteous prick about it?
