Riders should respect other motorists if we were to earn their respect. We should ride on the left side of the road as much as possible. There are no reasons that riders to conquer the whole road.
In a cycling event, marshal should not stop the traffic too long that will anger other motorists. From my experience, it happened a few times that the flow of traffic were stopped for very long until most of the motorists were out of their vehicles with angry faces.
No one should ride like this. The whole road was not meant only for them.
Unnecessarily blocked the traffic.
