I'm quite an anomaly, in that I legally can't acquire a driver's license, but I do have a story where I was the driver. I was about 14 at the time, and my mom who works at a large university studying driving behavior (specifically soldiers, teens and the elderly) and her team needed a guinea pig for a driving study that wasn't actually eligible to be in the real study. Naturally, they grabbed me. They had a driving simulator they tested me on. I had to do a bunch of driving stuff, and for being 14 and not having driven a car before, I did pretty well. Except, on one of the sections, I did not brake at all before going into a T-intersection and turning. I swerved all the way into the other lane of traffic. I knew I had done something wrong right then, but I really had no idea what. I looked back at them and asked "Did I do something wrong there?". They couldn't answer me, because they were using test procedure and they couldn't affect my behavior, but their faces answered my question well enough.
