Light over Westbloomfield, MI

The report, as filed

I was going to the store and looked up in the sky before getting in my car to see a single light, no blinking lights like on planes or helicopters, zoom past me overhead. I got in my car and followed it on my way to the store. Had no sense of scale for how big or fast the object was moving. It made zero sound, I tried hard to listen for helicopter blades but there were none, nor was there any sound from engines or turbulence. The object made a quick bank to the right almost completely horizontally, and then back to the left before altering it's original course. Why would a plane or helicopter change course and have no blinking lights and make no sound? If I were a pilot i would go straight to my destination, not bank to the right, then the left, then alter my course, it makes no sense.
