Vans of the Pit

So I was driving home from work today. Traffic was fairly heavy because it's construction season in Cleveland. Then this whole row of white vans, emergency lights flashing in unison even though they're going as fast as anybody else, pulls up and starts hovering alongside me. There are no windows except in the very front, just flat white metal, and they all have blank license plates. Now here's the creepy part: after a couple of miles, I look over to the on-ramp on my right, and TWO MORE blind cave vans accelerate into traffic, turn on their emergency lights, and merge into the line. I keep thinking, if only I had looked over there sooner, I would have seen the ray that transformed two ordinary cars into drone servants of the Van God. I suppose I should just be glad I got away unscathed. If they knew I was onto them...
