If I remember correctly, the first time I went driving with my newly acquired license (post-learner's permit) I just about bit it. Well, more likely, my passenger just about bit it. I probably would have been fine. Made a left without taking note of the oncoming traffic.
This isn't in any way an anti-car rant. Cars are useful things! But we do, I think, tend to brush aside the fact that cars are dangerous and lots of people die because of them.
