It's still a little bit unreal to me that most people don't have a license. When I moved here, 90% of the people I worked with didn't have a license or a car. And I came from a state where public transit sucked so driving was a need. Driving to me is one of the few freedoms I have left. It doesn't matter how I feel, all I have to do is hop in my car, hit the highway, and I instantly feel better.
I got my permit when I was 15 and then my license at 16. IIRC, it was $60 for drivers ed. classes, which is required to get your permit, and then $20 for the license. I missed one question on the written test and did perfect on the driving test.
Good luck to those taking the tests. Just remember, you control the car. The instant you think the car will bite you, it will.
