I think it's good to do something like this, but Stage One severely limits people.
Say I am about to start a family, and thus get an office job. I'll need to drive to do this. With these proposals, I wouldn't be able to sort it out for at least a year which can be detrimental.
Night restrictions for a year and passenger restrictions also fall into this. Say I have to work late, suddenly I can't drive home? My wife goes into labour at 2am, I can't drive her to the hospital.
Yes, one in five have an accident, but four in five do not. You should not punish the majority for the ineptitude of the minority.
A way around it is for there to be a driving centre in each county which has live simulations of various conditions, and tests based on that
