"My point is, what matters isn't who you are, or what category you fall into, it's what you do. (And about the worst common crime on the road is tailgating. Anyone of any age who drives too close to a car in front, meaning a speed where a collision would occur if the car in front ran into a block of concrete lying in the road, deserves to lose their licence for life.)" (McGrath of Harlow)

That is probably the most telling comment I have seen here. We all make mistakes. But it is the arrogant, "I know better than you," type of driving that kills people the most frequently.
