Bunch police or a motor bike moving with the main peleton would be the way to fix it (hopefully), but people will still cross the line on the long clear stretches.
I didn't think they tandem was as bad as some Flash. I know those guys quite well & rode round Long Bays with them yesterday. Their main problem is that they take a while to wind up, so once they do they look to make ground with it. Sometimes it meant going round people on the wrong side, but they didn't go over like some of those idots did on blind corners etc. They commented too that their brakes got a hell of a workout, and they take a bit more stopping than most. They had mechanical problems in the second half of the race too, so were a lot less prominent near the front. The stocker had his chain dropping down into the small chainring they were then having to stop pedalling and shift it back across by hand.
