Just curious - do other Prius drivers wave to you in your town? I notice A LOT of people are driving a Prius in the City and even more in the burbs now a days... and as of yet, only one driver has returned a wave. Maybe it's growing up in the south - people here seem to get flustered if you say "hello" when walking down the street too...
Actually I just got my first Prius wave returned a couple of weeks ago. But until recently I didn't see any other Prius in my area or commute. Wayne
