In giro they have radio communications from the team manager. In the Olympics they don't have that, they can't tell them the differences.

Also winning when the opponents are not really trying to catch you it's not really a story either. It happens a lot even when they know a rider is upfront in order to save energy for second place and not give a free ride to other cyclists -see how Carapaz won in men events where only Wout tried to catch him. The real story is the mistake from the dutch team that could have catch her but missinterpreted the situation.
