I am guessing that with tightening fuel economy rules, the rear window wipers became the standard as automakers were looking for ways to reduce drag.

But the Yaris rear wiper is so small, it is IMO really ineffective. Plus, all that crap on the rear after a rainstorm is really depressing to look at.

Huh! I just noticed (and read) IdahoTom's third post about the stability. I always thought my Yaris's squirrelly handling was due to the fact that it is FWD (I've had nothing but RWD cars until now) and just tought I would live with it. This alone is almost enough for me to scrap the deflector idea and buy and install VGs...
