I usually drive on an eight lane highway, including two HOV lanes. A cop\npassed me on the left, turned on his lights and did a sharp right.\nAnother cop entered the highway, with his lights on and starting driving\nin an S pattern across the highway, while slowing down to about twenty.\nHe kept this up for several miles, then just left the highway. Meanwhile\nthe first cop just took off at high speed. I can understand doing this\nto slow down traffic, but there were no incidents either way. Why would\nhe do this? I suspect the first cop just wanted a clear road so he could\ntest the sped of his car. The whole thing doesn't make any sense to me.\nI was tempted to turn on the video on my iPhone, but other drivers had\ngone into a "gotta get to the front first" mode.
