Testing the limits of the peaceful understanding and blanket tolerance the Pruis fanbase claims to practice, Toyota has released yet another spy shot that summarily reveals absolutely nothing. Like the first teaser shot (pictured above) that hit priuschat.com on Monday of last week, the new 2010 Prius teaser is so ambiguous it could be of just about anything, including what it most closely resembles – the open/close switch for the bathroom door on a commercial airliner.

Not schedule to be revealed in full until the Detroit Auto Show in January, early speculations about the hot button photo suggest the switch might power a retractable hard-top on the 2010 Prius, or possibly a sunroof feature. Personally, Toyota’s rich history in cutting edge technology has lent this photo a small amount of intrigue for me, and, as difficult as this is to admit, I am interested to see what larger purpose the seemingly bland button serves.
