I took my drivers licence when I was 35. I was freaking terrified. I was adult, conscientious, aware, a mother, a seasoned cyclist well used to duelling it out at close quarters with cars, trucks and motorcycles at high speed, and I was terrified I'd kill someone.
I realize now that much of that feeling was not having car handling under my skin, and now that I drive regularly I know the car and how to position it a lot better. But I try to never forget that feeling of how much you don't see from a drivers seat, and how very little time it takes to lose control. The feeling of danger I had was exaggerated, but still real and justified. I use that memory to remind myself to practice often and keep up my skills, and to actively judge if I should drive at all under difficult conditions.
I would welcome a compulsory re-test for a drivers licence after ten years. At age 16 (18 here) you may be old enough to master the physical act of driving, but at age 26 you're a responsible adult old enough to really come to grips with what you're doing and how it can affect lives.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
