USA has ass-backwards system for getting drivers license. At least from I could find online. You get learners permit after passing written exam. That’s not nearly enough. In my country you have to attend 20 hours (optional depending on existing licenses) of theory, then pass theoretical exam. Then you have a driving instructor assigned to you for total 40h (or 20h depending on existing licenses) in 1h sessions. You first start training court where you train to start, stop, turn and other driving maneuvers. When instructor deems you ready for traffic only then you get to drive with them in the car and having dual controls for the vehicle. Only when instructor deems you ready you are allowed to take the test for getting the license. And even on the test you first have to pass training court before you are allowed to enter traffic.
By the time you got learners permit you have at least 40h of driving in traffic which is significantly better than just passing written exam.
In my eyes, law is not the problem but experience and people paying attention. Phones, doing makeup, eating food and other things should be forbidden in car because it distracts you too much.
