Small orb with a cast off thin tail hovering on the street

Small orb like magenta colored light with a thin cast off tail that also was lit on the end levitating spinning above the street moving to the left. The closer we got we heard whistles, beeps wizzes in a metallic robotic melodic back and forth sounds like conversation. When our car drove over it we felt the sound under the car and then envelope the car and our space. When we passed over it the sounds faded and my rear window was clouded and I was not able to see it in the street. When we finally passed the area on the street I looked back out the rear window through the rear view mirror and the window appeared clean again.
