Instant Karma today. I'm driving down the highway, change lanes to pass a slow moving truck. As I get past, I can't get immediately back to the slow lane as there is a car merging on. There is a white Cadillac Escalade behind me, right on my ass and flashing his lights. As I pass the car merging on, I look over and think it's probably a cop, (plain grey Ford sedan with plain black tires, no hubcaps). I put on my turn signal and pull in front of him, going about 8-9kph over the limit. Before I complete my lane change, the Escalade goes flying past me. I am thinking, "if that was a cop, he should be going after that guy". Before I even finish that thought, the lights come on and he pulls over the Escalade. As I go by I can't help thinking, "serves you right, asshole".
