I have 3 cars in my driveway. My miev, a prius hybrid and a civic gas car. I noticed that a family of raccoons regularly like to hang out underneath the miev, but never under the other two cars. It doesn't matter where i position the cars, the raccoons always choose the miev to hang out under. Is there some kind of energy field that is active even when the car is off, and not charging? Also, why wouldn't they hang out under the Prius, it has a large battery as well, although not like the miev.
