Just driving fast will pick up rabbits, too. I had one on my tail the other night about 4 car lengths back at 80+ MPH. I agree that slowing down is the first option and I dropped down to 65. The doofus just assumed that I had a detector and slowed down with me. I didn't want to risk the triple digit ditch at night with no protection so I enjoyed their HID lights for 20 miles.
