I'd say, if you were hopeless at track driving before spending alot of time with a sim, you'd probably be a bit less hopeless after, but driving the car on the limit, "approaching your in game lap times", absolutely not.
There are many corners where the ideal line aims straight for the inner curb.
You shouldn't be on the inside if you didn't have overlap at turn-in, thus it should not happen, if there'd be a crash it would be your fault.
First tight left hander at Aston National for example, the line heads from outer curb straight to inner curb, cutting someone off is very simple, and not fun racing.
And in the corners where the outside line is "not-so-fast", slowing down enough to allow side-by-side traffic can render the inner line faster, so you're basically just letting a car pass (which, in my view, had not even started overtaking in the first place). Your philosophy seems to allow blatant cutting of someone's line, and suggesting the driver being cut off should just leave room because that's somehow safe and fun racing.
I'd say having simple prerequisites to when two drivers are supposed to organize taking a corner side by side, when to yield etc. is alot safer.
Many corners don't allow side-by-side traffic, anyone can "outbrake" into a tight corner on the inside, putting themselves basically onto the inner curb with 90% of the turning still left to do, the driver on the outside would basically need to stop and just let the "outbraking genius" get thru.
