A few minutes ago my wife was driving on a through street when a car started across the intersection in front of us. I gave a loud YEOW envisioning us broadsiding the other car. My wife had applied the brakes and stopped before crossing the path of the other vehicle. That driver had also seen us and had stopped before crossing our path.
Thump! thump! go our hearts still.
But think about some of the other scenarios. Suppose the through-street driver had been on a cell phone. Would that driver have reacted in time? Suppose the cross-street driver had been on a cell phone. Would that driver have reacted in time? What if the through-street driver had been speeding? That driver would not have reacted in time, especially if that driver had been on a cell phone.
This is a good example of how much attention is needed to drive safely. A cell phone requires too much of that attention. Hang up and drive!
