My friend got her driver's license in Germany when she was an adult. It was very expensive and she had to go through several courses. She had to prove that she could drive at night and during the day, and in a dense urban center, and also out on the highways, away from any cities. She was given multiple tests. It was a serious training effort.
This is the paradox of the American emphasis on freedom. The attitude tends to be juvenile. The American mindset, at its crudest, is something like, "You got to give me a car, man, because I'm free, man, I've got freedom, so give me a the right to drive man, authority sucks, man, the government sucks, I'm free so I can drive, you can't stop me, man." So the drivers are untrained, so the government responds by treating all drivers as if they are badly behaving children.
In Germany the attitude is "We (the government) will train you very well, and then we will trust you to be adults who can make wise choices."
One thing I never saw in Germany: cops hiding behind trees, hoping to catch people who were speeding. Traffic cops are very common in the USA, but basically unknown in Germany, since the major highways don't have speed limits.
Another thing I noticed in Germany, where there is a speed limit, people drive that limit, and not 5 kilometers above the speed limit. The drivers make the assumption that the government must have had some good reason for imposing a speed limit.
