I'm not sure if this has been noted in the past but I found this info on RF suppression for the Prius. http://www.sei.co.jp/tr_e/t_technical_e_pdf/61-02.pdf
I'm wondering if it has more to do with the widespread use of CAN (Controller Area Network) in the car? CAN is also used in industrial applications, where I'm familiar with them. The interconnect is all shielded cable. This also applies to other digital buses, such as Foundation FieldBus. http://www.turck-usa.com/Products/Networks...cifications.htm
