I was pretty wild when I was young. Especially in cars, some of the things we did we were lucky to survive, but when you are young you think you are invulnerable and better than any rally driver. I had better not repeat them as I would not want anyone to try them out. Youth is wasted on the young, it took me a long time to settle down. Nowadays I would say the biggest hazard while driving is touch screens. Whoever came up with them wants shooting. Driving wise the biggest external threat seems to me to be the proliferation of different modes of transport and their denial of any of the rules of the road applying to them. Oh, and texting on the move, especially cyclists.
