Nicely written!
It is clear that Zwift is putting a lot of effort into their Broadcasting Interface. What a milestone! The Tour on Zwift! Who, if not us Zwifters, would of thought that 4 years ago 
I remember a post I did where I said how cool it would have been to race the Stages of the Tour alongside of the Pro riders…we’ll get there!
I really like the live cameras and the new Ghosting feature, to highlight a specific rider, really neat. Having the PRO’ stats is also super cool.
I wish they could have replicated the environment a bit more though, it would have been nice to see the climbs packed with spectators, RVs/Caravans parked alongside the road and the devil at some point of the climbs, something not to hard to do in the actual state of Zwift. Something that would probably require more coding would be having spectators running along side the riders in certain segments and a cloud of smoke from flares like we usually see at the Dutch Corner and other Stages of the Tour.
Mike Woods posted a screenshot on Strava from Stage 2 and you can see the other riders jerseys alongside their names, this is also a cool feature that cold have been shown during the broadcast not to mention rolled out to us, mortals
Anyway, of course we’ll always ask for more but the advance being done so far is impressive. Looking forward to the future.
Ride On!
