Lights appeared in the NE, slowly moving towards SW, after pulling over my car to see better, they vanished.

I was on my way home from seeing family, and it was around 9:38 PM. As I was driving, I noticed what looked like the Pleiades star cluster to the North of me. However I thought it was odd, because they were unusually bright white and weren't in quite the right shape. As I continued driving, I noticed that the lights were separating from each other (from my estimate there were roughly ten lights) and they slowly formed a cigar shape. I continued to stare, and started to worry about going off the road, and as I was considering pulling over, I noticed that it seemed to be a single object, and was much closer than I thought it was. It was no more than a few hundred feet off the ground, and by that point it seemed to be about the size of a jetliner, but there were no lights to signify wings, nor any rumbling from a plane that size being so close to the ground. From what I could see, it looked quite angular, and there was a haze cast by the lights. I took my eyes off it for only a moment to pull over, and it was gone. I looked all around to see if maybe there was a light from a nearby residence that perhaps could have reflected off of my windshield, but I couldn't see any. After about 8 minutes of looking, I decided to continue on my way home.
