This is a picture I took of the Forbidden City Police force on a recent trip to China. These were among the only hybrids I saw there in two weeks of travel--the only other one I saw was also a Prius. I pulled this pic out of the video I took--sorry for the poor quality.
I wonder how badly the light bars effect FE?

Commuter car, grocery getter, and summer road tripper--average 10k miles per year.
Winter road trips and ski trips, bad weather commuter and my wife's "daily" driver--expected average 4k miles per year.
