so yesterday i was stuck on the highway during a really really bad accident. a CHP was coming up from behind on the left shoulder and i was in the middle or right lane. he left his radar on, and i was picking it up. i should've taken a picture, but i was using navi on my cell phone. anyways, i had 2 Ka signals from him, arrows facing the rear.. any idea why? could it have been a reflection off some car's windshield and hitting V1 also?
