it's because they are the best riders out there.. you should know that by now, no bike riding experience since the stabilisers came off now they are urban warriors with insane fixie skills...
Just push them at every junction, hold in front of them and pretend you are struggling. let them think they can take turn it up to go for a really tight light change and stop dead at the junction. When you pick them up off the floor suggest cycle training.
I prefer the smug cruising tactic. I simply cruise along at a moderate pace and watch the lycra sprint by. I then catch up with them sweating at the inevitable set of traffic lights where I smugly cruise by just as the lights turn back to green. This scenario repeats itself until they submit.
