Congratulations on being assimilated!
It's going to be interesting to see how many more people the Netflix series has really brought to cycling. That's obviously the idea that ASO (who organise the Tour de France and own the rights) had when they allowed Netflix's production teams in, but it'll be interesting to see longer term. One thing that Drive to Survive did for F1 was bring the racing back to the US, and in cycling the US is really deprived of top level racing right now, since the Tour of California died a while back. Indeed, Canada has more top level racing right now.
And yes, you've been spoiled by an excellent edition of the race this year. It's insane that there are so few seconds between the top two right now, and despite the shocker with the two motorbikes the other day, France TV who produce the pictures are unparalleled in covering cycling. Everybody else is a step below - often more than one step. And they've been covering this edition beautifully. Covering cycling live is vastly harder than any other sport, since it's on the move covering hundreds of kilometres a day, often in remote mountain passes where telecoms are very limited.
Phil Liggett has been calling the TDF for just about the entirety of my life. Seriously, before we got daily coverage in the UK back in the later 80s, we'd get highlights of the whole race one weekend on the big Saturday afternoon sports shows, and he was doing the race calling then. That all said, I fear he's a little long in the tooth, and he has been something of an apologist for Armstrong. I believe that with Peacock, you can change audio feeds, and the World Feed is also available, featuring Ant McCrossan. It's his commentaries that feature on the Netflix doc.
That said, sadly you're missing out on the Eurosport/Discovery+/GCN comms which have the superb Rob Hatch, Sean Kelly, Robbie McEwan and Dan Lloyd (but also Carlton Kirby - not so great), and ITV with Ned Boulting and David Millar. IMHO, both sets are much better than Phil, who last time I heard him, was just a little slow at picking things up, and is that much further away from the sport on a year round basis.
To be honest, there are enough good Americans in the current peleton to really need to jump back that much when speaking to a US audience. Sepp Kuss has been outstanding, and although he's not done anything much this Tour (and has said dumb things in the past), Quinn Simmons is a talent - although he withdrew last week. Throw in Neilson Powless who's still in the fight for polka dot (completely ignored in the Netflix doc) and Michael Woods' excellent victory for Canada, and there's plenty of good North American cycling right now!
Is there still doping in cycling? Probably some, and people do get caught. But I think cycling has its house in order much more than most sports. It feels that only when a sport has really been on its knees - like cycling and to a point track and field, - does it get taken seriously. I've never heard much spoken about football/soccer, but I'd be amazed if it didn't happen there. The same with tennis with Grand Slams played out sometimes over 4-5 hours like that.
Cyclists go faster these days because science has caught up with things like aero benefits, and sports nutrition evolves all the time. Cycling is about how you recover, and basically all of the TDF riders are on individual meal plans to allow them to get over mountains day after day. Allied to helmets, skinsuits, carbon fibre cockpits, rider positions on bikes, and all kinds of other "marginal gains" and Team Sky used to call them, and it means that riders can ride clean at the highest level.
As you've discovered, cycling can be a bit like cricket, or baseball, in that there are long periods where not a lot happens, but then it can suddenly catch fire and you're gripped by a half-hour mountain climb! But it needs those hours of not-a-lot to make the big moments what they are. It's only a fairly recent thing (within the last five years) that even the Tour de France had complete start-to-finish coverage. Production used to be only the last three hours or so, with perhaps the exception of the odd big mountain stage. But now we get everything, and that does mean that if a break goes immediately and the peleton lets it go on, say, a sprint day, then you're in for an awful lot of chateaus and not much else... :-)
