...at all the bikes piling up behind them as they spot the cop car and stop splitting! Happened twice on the way in this morning - heaps of bikes splitting along, then a whole lot concentrated together... because no-one wanted to be the first to split past the cop car. It's not as though the cops didn't catch us all in their mirrors before we spotted them. Once the cop had completely ignored a couple of heroes who hooked up the emergency lane at 60 (albeit with a quick flash of the brake lights in each case on spotting the cop car!) I figured they were unlikely to do anything about filtering stationary traffic and just headed off. but it must be pretty funny in all sorts of ways driving around in a cop car or riding a marked bike.
