Crazy Highway patrol

The highway patrol is decidedly crazier around these parts. Just as I was leaving the airport going peacefully along 101 (I've been told only people from San Francisco call it THE 101 and that other people call it 101) coming on the opposite side of the highway was a patrol car. What really struck me was that this patrol car was pacing traffic (very successfully I might add) by slaloming across the 4 lanes. And I'm not talking about your sunday slalom across a four lane highway, oh no, this patrol car was probably doing close to 60 and going from side to side in about 3 seconds.
