I have a strong suspicion that the reason "novice drivers" are more at risk on rural roads isn't entirely because they're "difficult" to drive (it's some of the easiest technical driving)... ... it's because as soon as they pass their test they start driving them too fast.

I don't know how these changes will remedy that, really. It'll prove they can drive the roads fine at the speed limit, which isn't hard, and then they'll pass their test and ... drive too fast. I guess more experience of going into corners at speed but, again, the issue will be too much speed and understeering, really common "early driver" crash type.
