On the main road that bisects my rural county, I typically lope along at 75 or so. This, to me – for me – is a reasonable speed. It’s within my comfort zone. Not so fast that I feel I’m pushing my limits as a driver – or the limits of the car. I state this as a mature adult who has taken several high-performance driving courses, drives professionally to earn my living (test driving/evaluating new cars) and who – most relevantly – has not had an accident in decades of driving. One of two things must be true: Either I am very lucky – or I am a responsible, careful driver.
