I haven't driven in other countries but from my experience I'm not sure this is translating to good driving on the road.

It covers some, lets say non-beginner situations that are pretty real and can make a difference between OK situation and multiple fatalities crash. A junior driver can still kill people as easily as anybody else, standards should be high.

And you should certainly drive in other countries, namely much worse and much better than yours (presumably US), they are both out there.
