More excuse finding. The Road Glide Customs presented the same headlight image as an automobile 0.8 miles away. For this analysis we get into trigonometry (from the Greek trigonon, meaning "triangle" and metron, meaning "measure"). I'll use 50" as a typical distance between headlights for an automobile. The distance between the two Harley lights is 8". Two headlights 50" apart and 0.8 mile away makes a long, narrow triangle. At which point along the triangle would two lights 8" apart fall? About 0.13 mile away, or 680 feet. That means when I pulled out to pass, the Harleys were about 225 yards down the road instead of 1,410 yards, or about 105 yards past the front bumper of the leading semi. (My apologies to those more familiar with metric units. We have yet to modernize our distance units here so we still have to multiply and divide by 5,280, 12 and 3.) To answer DesertTortoise's question " How long will it take for my passengers to see their life flash before their eyes?" With me going 90 mph and the Harleys going 75 it's about 3 Colorados before we close the gap. That is about the time I get passed the second car. My passengers better flash quickly.
