Don't see a previous thread with recommendations for best type of bike rack for Prius. Have always had roof rack with previous cars. I've always thought roof racks protected bikes better, but am sure that roof racks probably create more drag and bring the mileage down. I'd love to know the general consensus, if any. I know, I know, if I want to protect the bikes, put them inside! But sometimes just can't fit all of the gear and bikes inside. So, help!! Thanks
