I was driving in to work the other day, and was caught behind an enormous tractor-trailer truck trundling along at about 10 mph under the speed limit. Now, you know how I like to drive fast, and it’s always a challenge to curb my impatience and drive slowly. I looked at this behemoth in front of me, and it seemed to take up my entire field of view. The more I looked, the bigger it seemed until my whole world seemed to consist of this large, lumbering truck blocking my forward progress.
