Yeah but it doesn't have to be ON throughout the entirety of the track, otherwise the player is virtually on rails.
I often find I get better time straying off the driving line, not cutting corners, just trusting my instincts and reflexes over what some robotic prediction tells me to do.
All the visual information you need is your car slamming into a fucking guard rail for you to realize you overshot it. lol

I'm posting a new video soon that will hopefully settle this argument. I shaved three seconds off my laptime just chasing ghosts and feeling the track, at times even ignoring the cornering lines.
I'm someone who thinks it's a great tool for learning, but that it's no replacement for raw skill or familiarity with a track. That's why I think it's important to have as part of the options in a racing title. I don't think what you're saying is at odds with that, but you're responding as though it were.
If the cornering challenges work like I've seen, the game's own scoring system seems to recognize that people will react differently given the same info.
