You're complicating a simple act by suggesting riders from JV and QS were "adding to the congestion". They were on the opposite side of the pack to avoid the sprint chaos. The fact that they escaped was evidence they weren't pressing anyone and had the firepower to maintain a place while the sprinters spread ahead of them on the narrow and dangerous traffic-island zone.I'm sure this will make Remco even more popular in the peloton. No one's said it, but that counterpoint would be that Quickstep, Jumbo and Ineos are the teams most responsible for making things more dangerous by fighting for position on every flat stage and adding to the congestion. I understand why they do it, but you can't get involved in the fight and then go pointing fingers.
You can't take your hands off the bars to push another rider to create sprint space. If someone moves into you and you're buffering the impact to prevent a crash you may get a pass; if a crash is prevented. If you exacerbate a dangerous situation because you choose not to brake and back out of the space you are just a plain crazy sprinter and will have few friends.
Remco and Primoz had a brief but up front view of the ripple caused by Groves push-off on Ballerini. He's free to speak his mind when someone could have ended his GC for a sprint he had no chance to win.
