cars shouldn't drive past of course, but there's not really much you can do about a traffic jam like that, is there? It can always happen in races with a rolling road closure, and the peloton is usually aware of that.
there wasnt a moto marshall stopping the traffic though, or warning the riders of those obstructions, it was sat at the end of the queue for some reason in one of the clips I saw.
which creates a dangerous situation for the riders because you dont know whether the cars have stopped because they recognise theyre driving through a race and need to stop or not, and there will be riders in the peloton who are unsighted and when space compresses quickly thats how you get crashes, and riders then get more nervous and it kind of spirals out of feeling a safe racing environment
obviously the cars actually driving on the course alongside riders were more of an issue than the ones stopped, but certainly I think todays protest stoppage was because whilst the moto marshalls were doing better than yesterday they still werent stopping all vehicles, or warning the riders of them.
and in fact it carried on after the protest, theres a moment about 21ish km to go, there were two cars on the road coming towards the main group who were full width of the road, the 1st gets out of the way by about 20 secs onto a side road, the 2nd just has to drive into a gap off road at the last second as they pass, no sign of any moto marshall at all, there was another instance where they passed an on ramp and a car was trying to join the road with them, it at least had a moto marshall stopping it at the last second, but it only takes one vehicle in the wrong place to put the riders in serious danger. I was getting annoyed listening to GCN with the commentators whilst they were supporting the riders taking a stance, were trying to down play the race organisers responsibility for what was happening.
hopefully the Cyclists Alliance, or some of the more outspoken riders will send out some stronger worded messaging tonight, because weve still got another 126kms of this to go on a much flatter stage, and the race organisers clearly cant give guarantees its not going to keep happening.
