One cruiser literally just passed us by chance, then called in help.
He instantly hit the brakes and turned around. Eventually one passed us all, then stopped in the middle of the street, got out and pointed everyone over to the side of the road.
He did let a couple s2000's through.
The cops claimed they had complaints of some "passing" incidents, but had no descriptions of any of the cars doing it.
My guess is that they wanted us to go home.
