Unpopular Opinion? OK, no idea if thisll end up as unpopular, but we'll see.
Monza would be so much better if the entire track was about 2m wider. For the high-speeds, it's so easy for a car to park itself in a defensive position in series' like F1 and GTs. The first two chicanes are so narrow that going side-by-side through them is difficult and just leads to stupid pushing off of the other car and cutting the corners or collisions. Battles only continue after the corners of one car makes a mistake.
The first straight and corner is notorious in Sim racing for just being a crash every lap 1, and it's not much better in real life as you just need to watch the Blancpain crash from many years ago to see silliness at high speed. It's just a section where you are boxed into a position for a slow corner where if you've survived getting slowed down, any crash will be a silly clunk.
Widening that gives space for avoiding action and some different lines working. I'd never think I'd say this, but the Monza first chicane should be the same kind of radius and width as Jeddah's first chicane.
Curva Grande is too easy to push another car off track at 200mph while still being on the inside and not too far from the white line on the right. I'm not saying that drivers if given the width would suddenly stop pushing cars off, but it just seems that you don't even have to try hard to force someone off around the track, and it can make it almost too easy to defend if the cars have too much downforce/drag to make it a slipstream-fest kind of race.
