If your cop friend was riding towards me I'd swerve left and right about two feet so that he and the traffic behind me didn't know wtf was going on. Which is what he is doing, he doesn't know wtf is going on. I figure he'd either pull into the gutter and stop and I'd go around him or he'd swerve into oncoming traffic and I'd pull to the right. Then there's playing chicken and plowing right into each other. Seriously someone needs to educate the guy.
