What we do at 40mph to avoid an unseen obstacle in a canyon corner is a whole different deal than what they're doing at 10/10ths on a closed circuit.
I don't think they're always in every turn on the very edge of traction, especially not during a race. That would eat their tires pretty quickly. They might not be too far from it, but I'd think they're well within the margin (well within the margin as in the tiny margins that these people play with) to add something like for example a little counter-steer or a bit more throttle when exiting. Other times, when they're going for it, they are real close though, or over like Pedrosa in your example.
