It's funny to hear someone say this. I just went from a Toyota Camry (a relatively big car) to Toyota Prius-C, and I have the opposite feelings. Doing a shoulder check is very hard with the Prius, because of the weird back of the car. I now as a result hesitate driving it a lot, instead opting to use my brother's Corolla.

I do use the Prius in the city though, I easily get 75+ mpg when supermiling.
