I always try to find a safe place for me and the cop to pull over so that neither one of us gets killed or maimed.
You can see the ice and snow on the highway. They guy just wanted to keep his family from getting smashed to smithereens.
Icy highways are dangerous places to stop and mess around. Cops, of all people, ought to recognize this.
Pull over just far enough so the cop has to walk on the roadway to talk to get to your driver's door. If the cop wants you somewhere else make her give you explicit instructions where to go. Even then park in front of a puddle or snow drift.
