While I was in high school, a friend of mine said to me, “Cars are pretty damn dangerous.” It didn’t require any special powers of observation to see this, and so I replied, “They are, indeed.” Sensing that I wasn’t looking at it in the same way, my friend continued “Think about it, we’ve made it necessary that we use these two-ton steel blocks, and move them at speeds that consistently result in death or injury” (Car accidents cause approximately 30,000 deaths in the U.S. each year). He was right, but it wasn’t anything driver’s ed hadn’t taught me already. I knew/know the risk of driving, and try to follow the rules of the road to avoid aforementioned death or injury.
