I found you can push the 500 a lot harder than you think, if you're a fair bit away still it might just be that you've not found the limits in certain areas.
I can't see the vid above at the moment for some reason but I expect if you have a watch the driver is full throttle for most of the circuit! From what I remember you only need to brake for the hairpins, all the other corners should be taken at full throttle. You can let tyre scrub wash off a bit of speed on the last corner so you don't end up understeering off 👍
