^ I think if people used more common sense when driving there wouldn't be so many sucky drivers in the US.
I believe the rules vary state by state. I got my license in Michigan, which requires minors to go through a Graduated Drivers License (GDL) program. I had to take two segments of Drivers Ed, put in 60 hours of daytime driving and 20 hours of nighttime driving with a parent or responsible relative/friend aged 21 or older, pass both written exams for both DE segments, AND take a driving test with a cop before I got my driver's license, which altogether took over two years to get through the program and cost somewhere around $400

They're not as strict in Virginia, and I notice a huge difference in the quality of folks' driving skills

As far as the written test is concerned, I agree that it is mostly common sense and knowledge of traffic rules/laws and signs.
