I think most skins you can tell whos skin they are because of a certain style they have. ineX skins you know if its a ineX skin or not no matter whether its our first car, or the 2nd car. Same with GenR, ixion etc.
IMO it was a really good stream, with good commentating(the mistakes were funny, rather than annoying). The only improvement would maybe be a couple of interviews before the race starts, so maybe the commentators(and ofc people who arent already in an LFS background or whatever) actually have a chance to find out stuff about how the stategy will go through the race. Most people are already on TS for the race, so connecting to a different channel or ts server for a 1 minute chat 5 minutes before the race, especially if they arent the starting driver wouldnt be a big deal, and probably easier to organise that than an interview during the race. Just a suggestion anyways, I guess the future races will be harder to find the action without knowing the strategic side anyway.
