I don't drive a Prius. I know I should. But before I can even consider buying one, I need to share my feelings: Prii are too quiet! They sneak up on you in parking lots because you can't hear them and then you almost get run over!
(I hope you noticed that I said "Prii" when referring to more than one Prius -- according to Toyota, which released an official statement about this some time ago, "Prii" is the correct plural for Prius, not "Priuses." They didn't, however, specify the official collective noun for Prii...Please feel free to leave suggestions "A Pretentiousness of Prii," " A Pratfall of Prii"....)
