My own experience with Critical Mass in several cities in Europe has left me with mixed feelings. It’s one thing for a few cyclists in the stream to stand at an intersection and block traffic until the whole stream of hundreds of bikes has passed. But I have repeatedly seen cyclists not only block a car from passing the intersection, but begin thumping on its hood and shouting insults – and not because the car is trying to proceed, but because the cyclists are high on some sense of tribal unity. This does not boost public sympathy for cyclists, which is supposedly why we are all riding together in the first place.

The problem is perhaps that Critical Mass is a free-for-all where participants don’t have to participate in any initial orientation and be told “Please don’t be a jerk”. Any time human beings come together in big groups, that is a necessity, and cyclists are no exception.

I agree. That's why I prefer bike party vs. CM. CM feels like blocking cars for the heck of it.

yep :) love critical mass and the various bike parties (offshoot of CM). Related: https://www.harvard.com/book/two_wheels_good/ This book is such an amazing read for anyone into cycling.

Also all through Australia!
