They said that want to focus tracks that let drivers race more light and not that agressive, they want make people to stop driving agressive and make rammers less rammers somewhat
People will never stop driving aggressive in online games with little consequence for crashing, and no track selections will change that. Car selections probably contribute more to wrecking in lobbies anyways, because people who probably can't competently race Miatas will still try to drive GT3 cars because they think they are too cool for slow stuff.
Forza has always been a game that doesn't punish harshly for mistakes, meaning it heavily favors pace over all else with no strategy or punishment for abusing tires and so on. Add in that FM7 had a broken drafting system, and it has pushed the "culture" towards flat out attacking and making aggressive dives, and it will take some time for it to go the other way in FM8 (if it ever does).
Track-wise, Eagle Rock being an oval with a random V chicane in the back straight will very likely not be conducive to good clean racing. Long straight into low speed chicane is a formula that leads to crashes on lots of tracks (hello Monza), dunno why it would work any better on an oval. Plus, depending on how drafting works and what kind of cars you are driving, that will be the only braking point on the track, meaning people will get desperate on the brakes there.
Look at Daytona and Charlotte rovals, the chicanes in the back straight on those also cause some chaos in real life racing and tons of chaos in simracing, even in titles like iRacing that also have a safety rating system, and where your car can actually get totaled and put you out of the race, and you can even get banned if your move is stupid enough.
Sorry I wasn’t referring to its historical importance just from a pure racing standpoint, it’s extremely popular on sim racing and I’m not sure why
I think there are 2 main contributing factors to that.
1. It's a pretty straightforward track, so people feel like they have figured it out fairly quickly and it feels "safe" for them, even though T1 will be danger every time. Particularly in sim-ier titles, players are getting more and more risk averse when it comes to car and track selections and they don't really want things that will bite them, and Monza is a track where almost all of the danger comes from other drivers rather than the track itself.
2. It's a very "relevant" track for real-world series and quite prestigious. Basically everything races there, meaning it's a go-to track when running formula cars, multiclass endurance, GT, and touring cars.
It's kind of a weird track for me. For how simple and boring its layout looks, I find it surprisingly engaging to drive. Sure the first chicane sucks, but the second one can be satisfying to get right, and I find the Lesmos are one of most satisfying pairs of corners to nail in the world, particularly compared to how simple they look. Ascari is also actually kinda fun in the right kind of cars, too slow or too much downforce and it's too easy, but in something like GT1 it's also satisfying to get right.
Racing-wise though, I've had some good races there and almost every race I do features a few good battles... but they often only last a couple of laps, as inevitably someone gets punted into one of the chicanes, or someone misses their brakes a tiny bit and goes off track and gets a big slow down/penalty and drops back. It ends up being a bit of a roller-coaster, with some excitement/tension from good battles that becomes disappointment when things space out or I'm the one punted.
Monza was pretty boring in FM7 because of the wank drafting model, but in a game/car with good drafting it can make for very exciting races that become quite tactical. The importance of the draft there can be interesting for qualifying, as well as being a huge part of strategy races, as it's a thirsty track thanks to its high percentage of full throttle. For those reasons, coupled with the new emphasis on strategy in FM8, I would have put Monza higher up the priority list than places like Catalunya or Silverstone that are just kinda... tracks.
