On the one hand, it can be very helpful, for example when it is dark, it is hard to drive even for the experienced drivers too. That is why they need a mentor by their side. They can learn what, and what not to do in the circumstance at that moment.
On the other hand, there are parents who do not drive so they can not supervise their child. There are parents who do not have time, they work all day even on weekends. Having time is very important, too.
To sum up, I think young drivers SHOULD be supervised by their parents for at least a year because it is helpful for them and for the parents too. Parents would not worry that much and teens would learn to drive safely in the future.
