How to handle motorists' dangerous behaviour with an impassable group? I rode in a Velowagen (1) with over 300 cyclists on the national bike route in Switzerland, while on a narrow countryside road a few cars began piling behind us and one of them started trying to pass in an increasingly aggressive manner. At some point the left lane was free for a few meters and he started accelerating with the intent of klaxxonning (honking/blasting the horn) his way into getting a free lane as fast as he was moving. (2)   

To avoid a potential accident, my hotblooded reaction was to get in front of him and brake to force him to stop. After that and me nearly being run-over, the driver got out, almost started a fist fight, and a shouting match in French and Deutch followed between the two very angry of us, which very slowly allowed for a de-escalation and a safe distance to the convoy.   

In a similar situation, where a cyclist mass is blocking the road and drivers getting violent, how can the motorists be handled in a way that minimizes the risks ?



(1) A Velowagen is a big group of diverse cyclists going to a protest in another city. Includes every kind of riders : lycra, commuters, coursiers and families with children, so the global speed is around 15-20 kmh. The goal is not to intentionally block the road but to move across the country on the intended bike routes to keep the convoy safe.    

(2) While most cyclists were in the correct lane, a few were in the wrong lane to pass or because the group was very dense)
Don't create the situation in the first place. Every large event I've ever been on would either have the roads closed down, or send the riders out in waves so as not to create a situation where a car would have to pass so many cyclists at once.

Obviously the guy in the car was in the wrong, but there are still things that can be done to prevent the situation in the first place. Forming a defacto blockade on the road isn't really in anybody's best interest.
