They have to improve lot of things, and sometims the head of the group was important and they missed. Bad coverage in the mountains with good weather, and of course to give more information about km to go, gaps, etc...
But for a rider of most of those teams, imagine what great is to get home and watch a video of hours with him compiting with Lipowitch, Leknessund, Bennet, Froome, De la Cruz, Nizzolo...
I am from Burgos and use to watch Vuelta a Burgos, Vuelta a España, Clásica de San Sebastian, ...races with a very good organization, and for me was not normal to watch cars recently stoped on the roads, and lot of things like that, but they showed Sibiu region very well to the world, and the ITT was too technical, but showed very well the nice City Centre, without conditioning a lot the race. Anyway with rain no way.
