You know what? I think that this "strict regulation" about track limits in F1 2020 is not the same for everyone. I've done some time trial in Melbourne and then I did a comparison with these videos

Let's see the line taken in Turn 1, 4, 6 (entry and exit) and 10 (exit), but also in Turn 11 and 12 when you have to change direction: if I do the exact same line, I guarantee that I get an invalidation. Why in these videos James and TRL (just to mention two well know Youtubers) can do that line without having their laptimes invalidated? If I do that on my legit copy of F1 2020, every time I put only half a wheel (or even less) outside a kerb the game spoils my attempt. Not only in Australia, but in most of the track I've tried (Austria, Great Britain, Canada, Brazil ecc...). There's something strange (and unfair) about it, for sure.
