Obserbed bright disc in upper right quadrant of windshield as I was backing out of my drive, car was facing sough. As I drove eastward toward Detroit Metro Airport, object stayed in upper quadrant of windshield. As I stopped for traffic light at the intersesction of Wick and Middlebelt Roads, object stopped. I obserbed object through bare branches of a large tree across the intersection. As light changed to green, I proceeded through the intersection. A smaller bright disc-shaped object separated from the larger disc. Smaller disc proceeded due south at a very high rate of speed while the larger object changed to a southeasterly direction. I soon lost the object in the sun which by now had topped the trees in the area.
