I had just started to move out into the lane to ensure a car didn't try and take me in the roundabout. They were moving pretty quickly, I'd guess at least 40kph and I had no doubt they'd be turning. There was a good 30 in the group and if I didn't slow and almost stop, I would have collided with the rear half of the group. I didn't think to unclip and nearly had a clipstack.
this is why big groups are a bad idea, full stop. the lead riders can't feasibly be responsible for the actions of the following riders. and the following riders, particularly those surrounded by fellow riders, can't do anything but follow the group. so most of the bunch is essentially ballistic and hoping that nothing bad happens.
this is how that pedestrian on Beach Rd in Melb got killed - the rider couldn't stop for the red light as he had a marauding bunch behind him still going full speed.
