Depends on the country, but here teenagers are drilled so much during their L phase and on the cars with a manual transmission, so they are probably the safest drivers on the road.

Teens are roughly 3x worse than a 20 year old, and 10x worse than a 50 year old.
There are plenty of things that come with experience vs book learning that makes a safer driver. A freshly licensed teen comes with none of that. They also have the natural tendency of having high risk tolerance which makes decision making different than an older/exeprienced driver that is more risk averse.
I'm in North Texas, so I have a personal rule that if the temps are forecasted to be below freezing with any form of precipitation, I do not leave the house. People make moronic decisions on how to drive in those conditions because it doesn't happen enough and as a collective, proper ability to drive is forgotten every single time.
It's a trick question. You don't should be the response.
For those that do, my first question is what is so damn important that you have to be driving in icy conditions in the first place? Schools are closed. Most businesses are closed. If my business isn't closed, I use a personal day. This isn't Chicago/Minneapolis where the snow lasts for 3 months. This is N. Texas. It's typically only cold enough for these conditions for a couple of days and typically only at night. Which actually makes it worse as it melts in the day, refreezes overnight, and people forget about the refreeze and drive as if things are normal.
Why would you assume that a driver's education is a matter of book learning? Is that how you were taught?
We had book(lets) that we had to read from to learn the rules/laws of the road. There were quizzes/tests to be taken during those classes in order to pass the class. Once the class was passed, I then had to take a written exam issued by the state. That was followed by an actual driving test with a state official in the car.
So assuming based on my personal experience. I know the times have changed, and you no longer have to do silly things like learn how to drive or be required to wear shoes while driving in today's world.
Luckily for me I had been driving for a while and I was tested initially in a more rigorous country, I was just getting my license after I moved to the US, but it explains a lot of what I see in the streets.
