Prius's have a way of automatically making the driver self righteous and one of the biggest pricks in the land. Like they can do no wrong - and that they alone are saving the environment by driving a Prius (ignoring all the pollution caused in the making of the battery of the car).
The other thing about following a Prius - prepared to go very slow. Prius's are 3rd on the list of cars you don't want to be behind unless you want to go 10 MPH below the posted limit - the other two are Buick's and Minivans.
Smartcars didnt make the list:shrug:
