Isn't that what learner's permits are? In my state, you need a minimum of I believe 40 hours of driving with an over-21 adult that they sign off on, then completing a driving class with an instructor, and over however many sessions they judge your driving, and after that you get your license. In my experience the student drivers were the ones staying strictly to the speed limit, always using indicators, etc. When I first started driving I was hyper-focused on not breaking the rules, paying attention to the road. The ones who are the worst are the people who think they know how to drive well, so they are on their phone or half-asleep while driving.
