As a by-the-by, two teams involved in a fleche here in Australia -- a 24-hour time trial -- were rubbed out for not abiding by the rules. They pleaded ignorance and/or safety as to why they broke the rules. They appealed, became quite aggressive when challenged on their flimsy evidence, and they simply could not see that they had done anything significantly wrong. As one of the people who sat on the appeal panel, I was as disappointed in their lack of contrition as anything else.
In the context of this discussion, Strava files were used to build the evidence against the team, along with ego-boosting videos of one of the teams' ride.
