Or at least one. I was on a freeway yesterday, driving in the left lane and whenever a certain motorhome was next to me, the ultrasonic proximity sensor rings showed red and the car moved away to the extent of driving on the left yellow line. The car moved back when the motorhome passed or when I passed it (this happened several times.) My wife and I thought it was quite amusing that the car was so fearful of the motorhome. It is not like it was encroaching on our late or anything; it was centered properly in its lane. I've never seen anything like this before.
