I do too, when I can. I was in a tight little knot of traffic that was watching the police car in their midst. I also figured that slowing down would look suspicious. Catch 22.
Probably true. I've heard of cops pulling over drivers because they were "suspiciously" driving under the speed limit. Glad you got out of there ok. Innocent citizens in a free society should not fear the police; sadly this is becoming less the case.
