Not sure if this is the best thread to ask as it applies to all the teams (im sure), but why all of a sudden now on the rear wings teams have these small luminious stickers in pretty much the same places across the teams that are doing it on the rear wing? Is it more for Liberty Media and needing some reference points for car tracking for certain graphic packages that we are seeing now such as onboard cameras that track and annotate the leading car they are trying to catch?
Just thought I would ask here since its more obvious on the F1-75 given their naked carbon rear wing, plus most development interest discussion this season will be for the Ferrari and Redbull.
